No. Python is very close to "English-like", but not exactly, and this is
one of the easiest places to trip.

In English:

"the cat is in the box or the cupboard or the kitchen"

means:

"the cat is in the box, or the cat is in the cupboard, or the cat is in
the kitchen".


But that is not how Python works. In Python, you have to say:

cat in box or cat in cupboard or cat in kitchen


Although this will work as well:

any(cat in place for place in (box, cupboard, kitchen))


In Python, an expression like this:

cat in (box or cupboard or kitchen)


has a completely different meaning. First, the expression in the round
brackets is evaluated:

(box or cupboard or kitchen)


and then the test is performed:

cat in (result of the above)


The expression (box or cupboard or kitchen) means "return the first one
of box, cupboard, kitchen that is a truthy value, otherwise the last
value". Truthy values are those which are considered to be "like True":

truthy values:

- True
- object()
- numbers apart from zero
- non-empty strings
- non-empty lists
- non-empty sets
- non-empty dicts
- etc.

falsey:

- False
- None
- zero (0, 0.0, Decimal(0), Fraction(0), etc.)
- empty string
- empty list
- empty set
- empty dict
- etc.

(Can you see the pattern?)


So you can experiment with this yourself:

42 or 23 or "foo"
=> the first object is truthy, so it is returned

0 or 23 or "foo"
=> the first object is falsey, and the second object is truthy,
so it is returned

0 or [] or "foo"
=> the first two objects are falsey, so the third is returned


The "and" operator works in a similar fashion. Experiment with it and see
how it works for yourself.


I read yours psots many times,all of them, tryign to understand them.


if '-' not in ( name and month and year ):
			cur.execute( '''SELECT * FROM works WHERE clientsID = (SELECT id FROM 
clients WHERE name = %s) and MONTH(lastvisit) = %s and YEAR(lastvisit) = 
%s ORDER BY lastvisit ASC''', (name, month, year) )

elif '-' not in ( name and year ):
			cur.execute( '''SELECT * FROM works WHERE clientsID = (SELECT id FROM 
clients WHERE name = %s) and YEAR(lastvisit) = %s ORDER BY lastvisit 
ASC''', (name, year) )

elif '-' not in ( month and year ):
			cur.execute( '''SELECT * FROM works WHERE MONTH(lastvisit) = %s and 
YEAR(lastvisit) = %s ORDER BY lastvisit ASC''', (month, year) )

elif '-' not in year:
			cur.execute( '''SELECT * FROM works WHERE YEAR(lastvisit) = %s ORDER 
BY lastvisit ASC''', year )


==

i just want 4 cases to examine so correct execute to be run:

i'm reading and reading and reading this all over:

if '-' not in ( name and month and year ):

and i cant comprehend it.

While it seems so beutifull saying:

if character '-' aint contained in string name , neither in string month 
neither in string year.


But it just doesn't work like this.

Since  ( name and month and year ) are all truthy values, what is 
returned by this expression to be checked if it cotnains '=' within it?

No! That creates a string from 16474 in base two:

'0b10001011010'

The leading 0b is just syntax to tell you "this is base 2, not base 8 
(0o) or base 10 or base 16 (0x)". Also, leading zero bits are dropped.

Then you encode the string '0b10001011010' into UTF-8. There are 17 
characters in this string, and they are all ASCII characters to they take 
up 1 byte each, giving you bytes b'0b10001011010' (in ASCII form). In 
hex form, they are:

b'\x30\x62\x31\x30\x30\x30\x30\x30\x30\x30\x31\x30\x31\x31\x30\x31\x30'

which takes up a lot more room, which is why Python prefers to show ASCII 
characters as characters rather than as hex.

What you want is:

chr(16474).encode('utf-8')


[...]

No. There are 17 BYTES there. The string "0" doesn't get turned into a 
single bit. It still takes up a full byte, 0x30, which is 8 bits.

Correct.

the following bytes:

  >>> bin(16474).encode('utf-8')

An observations here that you please confirm as valid.

1. A code-point and the code-point's ordinal value are associated into a 
Unicode charset. They have the so called 1:1 mapping.


So, i was under the impression that by encoding the code-point into 
utf-8 was the same as encoding the code-point's ordinal value into utf-8.


That is why i tried to:
bin(16474).encode('utf-8') instead of chr(16474).encode('utf-8')

So, now i believe they are two different things.
The code-point *is what actually* needs to be encoded and *not* its 
ordinal value.




The leading 0b is just syntax to tell you "this is base 2, not base 8
(0o) or base 10 or base 16 (0x)". Also, leading zero bits are dropped.


But byte objects are represented as '\x' instead of the aforementioned 
'0x'. Why is that?

I disagree here.
16474 is a number in base 10. Doing bin(16474) we get the binary 
representation of number 16474 and not a string.

Why you say we receive a string while python presents a binary number?



Then you encode the string '0b10001011010' into UTF-8. There are 17
characters in this string, and they are all ASCII characters to they take
up 1 byte each, giving you bytes b'0b10001011010' (in ASCII form).


0b10001011010 stands for a number in base 2 for me not as a string.

In Python 2:

In Python 3, you have to fiddle around with ctypes, but broadly

Here's a link [1] to Chris' original question (and the following answers
including mine which mentioned Think Python).

Chris' requirements were slightly different. In your case "Python for Kids
- A Playful Introduction to Programming" [2] might be more appropriate as a
first book. Despite the title it covers a wide range of topics
*specifically geared towards writing a game in Python*. See the detailed
table of contents to help decide.

Also Chris has an "unnatural" abhorrence of Python 2.7 :) --- at least as
far as learning Python books. As such he dismissed too early what I think
might be a great initial (or 2nd) book, Hello Python [3]. To requote the
Preface which resonates at least with me:

"I thought back to how I first learned to program. I didn't read an
entire programming book from cover to cover and then write a program
after I knew everything there was to know. Instead I started with a
goal, something that I wanted to do, and worked toward it, figuring
things out as I went. I read programming books from time to time,
but really only to figure out the bits I was stuck on. When I was
done, my programs weren't particularly elegant or fast, but they
were mine---I knew how they worked, and they solved a real problem
that I was having."

Some chapter titles include "Gaming with Pyglet", "Twisted Networking"
(which implements a MUD), and "Django" so it covers quite a bit of ground.
Again see the detailed table of contents.

Notice that the subtitle for Think Python [4] is "How to Think Like a
Computer Scientist" which is not every beginning programmer's goal. Yes,
Think Python is free, and yes it's probably quite good, but it's not for
everyone. In particular the presentation is a lot drier than the above
mentioned books.

Somewhat offtopic but mentioned in the thread: Here's what Elliotte Rusty
Harold had to say about Java Console IO in Java I/O, 2nd Edition (OReilly,
2006) which I recently read while helping somewith with their college Java
(yuck!) homework:

Many common misconceptions about I/O occur because most programmers'
first exposure to I/O is through the console. The console is
convenient for quick hacks and toy examples commonly found in
textbooks, and I will use it for that in this book, but it's really
a very unusual source of input and destination for output, and good
Java programs avoid it. It behaves almost, but not completely,
unlike anything else you'd want to read from or write to. While
consoles make convenient examples in programming texts like this
one, they're a horrible user interface and really have little place
in modern programs. Users are more comfortable with a well-designed
GUI. Furthermore, the console is unreliable across platforms. Many
smaller devices such as Palm Pilots and cell phones have no
console. Web browsers running applets sometimes provide a console
that can be used for output. However, this is hidden by default,
normally cannot be used for input, and is not available in all
browsers on all platforms.

Yikes, a bit opinionated isn't he? Reminds me of some people on this list :)

Finally, regarding sneering at HTML/Javascript. While I've never used the
technology, HTML5/Javascript has the Canvas and possibly WebGL. I've
noticed all sorts of new books on the topic, for example:

Core HTML5 Canvas  Graphics, Animation, and Game Development (Prentice
Hall, 2012)

HTML5 Games Development by Example - Beginner's Guide (Packt, 2011)

HTML5 Games Most Wanted (Friends of Ed, 2012)

Supercharged JavaScript Graphics - With HTML5 Canvas, jQuery, and More
(O'Reilly, 2011)

HTML5 Graphics and Data Visualization Cookbook (Packt, 2012)

This in fact "may" be/is the future of graphics programming (at least in
terms of # of apps written)? And TypeScript [5] "may" make using javascript
(under the hood) less objectionable.

I still agree with your overall approach, learn programming via Python
first --- not for god's sake Java, which colleges still think is the bee's
knees :). But realize that it's only one tool in the programmer's toolkit
and you'll eventually have to learn many languages.

Thanks for hunting that thread down, I probably should have back when
I mentioned it :)

As to my abhorrence of Py2 - I don't hate the language (and do use it
at times), but if someone's going to learn programming, s/he should
really learn from something with native Unicode strings. Yes, you
could use Python 2 and open with some future directives, but unless
the course/book is written with that in mind, you'll end up having to
unlearn and relearn to master true Unicode handling. No point doing
that when you can just learn on Python 3!

Hi Wolfgang

I share your passion for empowering a human operator to complete and submit 
a form as quickly as possible. I therefore agree that one should be able to 
complete a form using the keyboard only.

There is an aspect I am unsure of, and would appreciate any feedback based 
on your experience.

I am talking about what I call 'field-by-field validation'. Each field could 
have one or more checks to ensure that the input is valid. Some can be done 
on the client (e.g. value must be numeric), others require a round-trip to 
the server (e.g. account number must exist on file). Some applications defer 
the server-side checks until the entire form is submitted, others perform 
the checks in-line. My preference is for the latter.

I agree with Chris that on a LAN, it makes little or no difference whether 
the client side is running a web browser or a traditional gui interface. On 
a WAN, there could be a latency problem. Ideally an application should be 
capable of servicing a local client or a remote client, so it is not easy to 
find the right balance.

Do you have strong views on which is the preferred approach.

Thanks for any input.

Frank Millman

I disagree here.
16474 is a number in base 10. Doing bin(16474) we get the binary
representation of number 16474 and not a string.
Why you say we receive a string while python presents a binary number?



You can disagree all you like. Steven cited a simple point of fact,
one which can be verified in any Python interpreter. Nikos, you are
flat wrong here; bin(16474) creates a string.



Indeed python embraced it in single quoting '0b10001011010' and not as
0b10001011010 which in fact makes it a string.

But since bin(16474) seems to create a string rather than an expected
number(at leat into my mind) then how do we get the binary representation of
the number 16474 as a number?


In Python 2:

16474
typing 16474 in interactive session both in python 2 and 3 gives back 
the number 16474


while we want the the binary representation of the number 16474

Indeed. 5-byte and 6-byte sequences were originally part of the UTF-8
specification, allowing for 31 bits. Later revisions of the standard
imposed the UTF-16 limit on Unicode as a whole.

How to pass instance into decorator function

[Jayakrishnan Damodaran]

I have a class which calculates some salary allowances. Instead of a blind 
calculation I need to check some conditions before I can return the calculated 
amount. Like if all the allowances calculated till now plus the one in progress 
must not exceed the total salary(this may occur since these allowances are a 
percentage of basic pay). Below is a sample code FYI

class CompanySalaryBreakUpRule(object):
'''Class to calculate the various salary components.
This class is inherited by individual company classes whom implement salary 
calculations.
Various component calculations are implemented as @property and hence be 
accessed as class properties.

'''
grossPay = 0.0
remainingAmount = 0.0

def checkValid(self, func):
from functools import wraps

@wraps(func)
def wrapper(self, *args, **kwargs):
allowanceToCheck = func(self, *args, **kwargs)
if allowanceToCheck > self.remainingAmount:
allowanceToCheck = self.remainingAmount
else:
self.remainingAmount = self.remainingAmount - allowanceToCheck
return allowanceToCheck
return wrapper

@property
@checkValid
def dearnessAllowance(self):
return self.basic * 0.2 # we have a function that calculates basic pay

But executing this raises an exception
@checkValid

This really doesn't have anything to do with python.  Someplace like 
http://en.wikipedia.org/wiki/Comparison_of_version_control_systems would 
be a good starting point for further research.

If I were to buy a closed-source VCS today, I would look at Perforce 
(www.perforce.com).  I used it for several years.  For small teams, you 
can download and use it for free, so you can play with it without 
commitment.

Perforce tries to solve a somewhat larger problem than just version 
control.  They also do configuration management.  You can set up a 
config-spec which says, "Give me this bunch of files from branch A, that 
bunch of files from branch B, and some third bunch of files which have 
some specific tag.  And, while you're at it, remap the path names so the 
directory structure looks like I want it to".

This configuration management can be a powerful tool when working on a 
huge project.  We threw *everything* into our p4 repo, including the all 
the compilers, development toolchains, and pre-built binaries for all 
the third-party libraries we used.  We also used a single repo shared by 
all the development groups (many 100's of developers on three 
continents).  I would never want to do that in a system like git or hg; 
every developer would have to drag down 100's of GB of crap they didn't 
need.  With p4, we could build people config-specs so they got just the 
parts they needed.

It is also a bit of a steep learning curve to figure out.  Only a few 
people were trusted to do things like build config-specs and create 
shared branches.

As a company, Perforce is a dream to work with.  Their tech support was 
pretty awesome.  I would shoot off an email to supp...@perforce.com, and 
I don't think it ever took more than 5 or 10 minutes for me to get a 
response back from somebody.  And that somebody would inevitably be 
somebody who knew enough to solve my problem, not just some first-line 
support drone.

The costs aren't outrageous, either.  The pricing is a little 
complicated (initial license, annual renewal, various support options, 
of them on a sliding scale based on quantity).  I seem to remember it 
working out to about $100/developer/year for us, but we were buying in 
fairly large quantities.

Remember that

@checkValid
def dearnessAllowance(self): 
...

is a shortcut for

def dearnessAllowance(self): 
...
dearnessAllowance = checkValid(dearnessAllowance)

The function call happens in the class body, so checkValid() is still normal 
function that has knowlegde neither about the class nor (as the self arg 
implies) about an instance of that class. 
While it would be sufficient to remove its first argument

> class CompanySalaryBreakUpRule(object):

I recommend that you also move it out of the class body:

  def checkValid(func):

Python does not work that way. Ints *always* display in decimal. 
Regardless of whether you enter the decimal in binary:

py> 0b10001011010
16474


octal:

py> 0o40132
16474


or hexadecimal:

py> 0x405A
16474


ints always display in decimal. The only way to display in another base 
is to build a string showing what the int would look like in a different 
base:

py> hex(16474)
'0x405a'

Notice that the return value of bin, oct and hex are all strings. If they 
were ints, then they would display in decimal, defeating the purpose!

neither being by any means dead. And "glass teletype" is still the

The position in space is represented as a vector, which is then used in a

Currently I'm using numpy arrays to represent vectors.

This was already covered three days ago in another post in this thread.  
I'll quote the post below


I've tested the following:


model = Model()
model.points.append(Point(1,2))
model.points.append(Point(1,4))

line = Line( model.points[0], model.points[1])

# Case A: this works
model.points[0].position = [2,3,4]
line.points

# Case B: this doesn't work
test.model.points[0] = test.Point(5,4,7)
line.points



Is there a Python way of getting the same effect with Case B?

I would say that SVN does have its uses, but managing software repositories 
isn't one of them due to the wealth of available alternatives out there

I agree, but there is a feature Git provides right out of the box which is

So, I guess the next questions is, why would you *want* to merge 
multiple branches in one pass?  What's the use case?  I've been using 
VCSs for a long time (I've used RCS, CVS, ClearCase, SVN (briefly), 
Perforce, Git, and hg).  I can't ever remember a time when I've wanted 
to do such a thing.  Maybe it's the kind of thing that makes sense on a 
huge distributed project with hundreds of people committing patches 
willy-nilly?

How would hg even represent such a multi-way merge?  Doesn't every 
revision have exactly one or two parents?

Some views of mine (controversial!).

Python is at least two things, a language and a culture.
As a language its exceptionally dogma-neutral.
You can do OO or FP, throwaway one-off scripts or long-term system
building etc

However as a culture it seems to prefer the OO style to the FP style.
This is unfortunate given that OO is on the down and FP is on a rise.
Some thoughts re OOP: 
http://blog.languager.org/2012/07/we-dont-need-no-o-orientation-4.html

So my suggestion is use some rigorous FPL like Haskell to learn/teach
programming.
After that you can switch to python or some other realistic language.

Note: I have some serious reservations regarding Haskell
http://blog.languager.org/2012/08/functional-programming-philosophical.html
Nevertheless it seems to be the best there is at the moment.

tl;dr: Haskell is in 2013 what Pascal was in 1970 -- good for
programming pedagogy.

Must we include urllib just to decode a URL-encoded string, when using Requests?

[Dotan Cohen]

I am using the Requests module to access remote URLs. Sometimes I need
to URL-decode or URL-encode a string (via RFC 3986). Must I import
urllib or urllib2 just to use their quote() and unquote() methods?
Does not Requests have such an ability, and perhaps I just cannot find
it?

On Stack Overflow [1] I found this wonderful function:
def unquote(url):
  return re.compile('%([0-9a-fA-F]{2})',re.M).sub(lambda m:
chr(int(m.group(1),16)), url)

I am already importing the 're' module so that is not an issue. I am
concerned, though, that this might not work for some non-ASCII
characters such as some esoteric symbols or Korean/Chinese/Japanese
characters.

This is true of all languages.  Hang out on the PHP, Ruby, Python, etc, 
forums and you quickly learn that the cultures are as different (or more 
so) than the languages.

The same is true for the human race.  The human race is what it is 
partly because of the DNA we mix-and-match every generation, but also 
because of the information we pass from brain to brain.  Neither one 
tells the full story of what we are.

No, it doesn't. It gets its quote() function from urllib always.

The only thing I can think that you are talking about is the difference between 
Python 2 and Python 3. In Python 2, it's urllib.quote() and in Python 3, it's 
urllib.parse.quote(), but that's a Python-version issue, not something to do 
with requests, per se. requests does have a compatibility layer, internally, 
that pastes over those issues, but I don't think that is intended to be a stable 
public API that you should rely on. You should handle that kind of switch 
yourself if you care about compatibility across both versions of Python.

Umm... Of course. I dont know though how that relates to the OP's
question.
So let me try state my point differently:

Python-the-language has strengths that are undermined by the biases in
the culture of Python.

Great, thank you Robert. I see that Requests is calling both urllib
and urllib2. For some reason I thought that is rather wasteful and
should be avoided. I was probably wrong!

paste this to your python console, it'll show you what modules requests

It's not either-or. The server *MUST* perform the checks at the time
of form submission; the question is whether or not to perform
duplicate checks earlier. This is an absolute rule of anything where
the client is capable of being tampered with, and technically, you
could violate it on a closed system; but it's so easy to migrate from
closed system to diverse system without adding all the appropriate
checks, so just have the checks from the beginning.

In terms of software usability, either is acceptable, but do make sure
the user can continue working with the form even if there's latency
talking to the server - don't force him/her to wait while you check if
the previous field was valid. I know that seems obvious, but
apparently not to everyone, as there are forms out there that violate
this...

So, now i believe they are two different things.
The code-point *is what actually* needs to be encoded and *not* its

But byte objects are represented as '\x' instead of the aforementioned 
'0x'. Why is that?



ints always display in decimal. The only way to display in another base
is to build a string showing what the int would look like in a different
base:

py> hex(16474)
'0x405a'

Notice that the return value of bin, oct and hex are all strings. If they
were ints, then they would display in decimal, defeating the purpose!


Thank you didn't knew that! indeed it working like this.

To encode a number we have to turn it into a string first.

"16474".encode('utf-8')
b'16474'

That 'b' stand for bytes.
How can i view this byte's object representation as hex() or as bin()?


Also:
>>> len('0b10001011010')
17

You said this string consists of 17 chars.
Why the leading syntax of '0b' counts as bits as well? Shouldn't be 15 
bits instead of 17?

i just want 4 cases to examine so correct execute to be run:

i'm reading and reading and reading this all over:

if '-' not in ( name and month and year ):

and i cant comprehend it.

While it seems so beautiful saying:

if character '-' ain't contained in string name , neither in string 
month neither in string year.


But it just doesn't work like this.

Since  ( name and month and year ) are all truthy values, what is 
returned by this expression to be checked if it cotnains '=' within it?

Wrong. The "'=' not in (...)" first evaluates the expression in
parentheses, that's what parentheses are for. And then it looks for '='
in the result. And that result is just one of the three values, MRAB
told you which one.


okey first the expression eval:

( name and month and year ) = ( name=True and month=True and year=True )


No. Read MRABs post, he explains it. Or work through the tutorial. This
would be right in another language, but not in Python.

If this expression would really evaluate to True or False, you
definitely couldn't search for any character in the result.

As it is, it evaluates to a string or to None, but searching for '=' in
that string doesn't give the result you think it does.


(name and month and year) is a Boolean expression, correct?

It will return True if all three are True and False otherwise. I cannot 
use it the way i desire regardless of how logical i think it looks.


Basically its just like i'am saying:


if "-" in True:
or
if "-" in False:

Obviously when i write it this way you can see it makes no sense.

==
But (name or month or year) is also a Boolean expression.

It will return the first of the three depending which value comes first 
as truthy.

it will return False if none of the three are False.

So how am i going to write it that?

if '-' not in name and '-' not in month and '-' not in year:  ??

Nikos, please, DO NOT DO THIS.

It must be clear to you that Steven is *much* more experienced than
you. Your presumptions about what he can and can't do with the access
you give him are therefore not much more than uninformed guesswork.

You have already been give a lesson about trusting the care of your

and Chris, who gave you that lesson, is telling you that the course of
action you propose is unwise.

Steven has given every impression, over a long period, of being one of
the good guys, but *you don't know him*, and *you don't have any kind
of legal agreement with him* that would protect you should he turn out
to be malicious[1].

Given what's already happened to you, it would be the height of
irresponsibility to continue as you propose. If I were one of your
clients and I found out about it, I'd be seriously considering legal
action against you for gross negligence.

With the following code tweaks in Python 2.7.2, I find it works with VERBOSE

I would say the regex could still use some more adjustments yet.

myDetails = [ m.groupdict() for m in regex.finditer(inp)][0]

Do you see that it prepends your nikos path the your dauwin path and file
name.  It isn't replacing one with the other.  Somewhere in your SFBI mess
of code you perhaps have set the nikos path as the start of a filename.
Check that out

If he (son) learns Haskell, he may as well stay with it, because it's 
quite decent lang as far as I can tell. And it's compiled, too.

I would also consider Racket, which is a Scheme superset. It too, comes 
with compiler/JIT, plus IDE, plus libraries plus I understand examples 
from "Structure and Interpretation of Computer Programs", 
( http://mitpress.mit.edu/sicp/ ) can be run on it. I have heard some 
folks are doing real life stuff with it, too and IDE might help beginner a 
lot (this one is very nice, not just magnified editor).

I agree that branch/merge handling in svn is primitive compared to git
(haven't used hg enough to comment).

The last time we made the choice (4-5 years ago), Windows support for
get, bzr, and hg was definitely lacking compared to svn.  The lack of
something like tortoisesvn for hg/git/bzr was a killer.  It looks like
the situation has improved since then, but I'd be curious to hear from
people who do their development on Windows.

That's what you _think_ you're offering.

Unless you're are a very careful, very experienced system admin -- and
you're also lucky -- you're probably wrong.  If not now, then you'll
be wrong next week or next month when a new privelege elevation
exploit is discovered for your OS.

Of course kids are more interesting in things painted on
screen, especially if they are colorful, move and make
sounds at that. The next step would be a simple, 
interactive game.

Which is why I would synthesize something neat yet
simple from http://processing.org/tutorials/

Python is overkill for a kid. Ugh. Some people have just
no common sense at all.

I am implying that your demonstrated lack of ability means that *you
don't know* what Steven or anyone else could do with user-level
access. Elsewhere on this list, you've been shown that you're
publishing database passwords to the whole world in plaintext. Who

And you have presumably informed all your clients that you're letting
the second complete stranger in a week into their data, passed on to
them the warnings you have received against doing exactly that,
reminded them that the last time you did so you were severely
embarrassed by the result (and that you're not skilled or experienced
enough to be sure that nothing worse happened), and secured their
go-ahead, right?

There is a book "Python for Kids" that I haven't looked at, from No
Starch Press.  You might check into it.

You might also look at the game Code Hero, which teaches kids to program
games with Unity3D and Javascript.

All kids can be fit into the stereotype -- 'kid'??

I can tell you after 25 years teaching programming --
Some kids will take to FP, others will not
Some will take to C, some wont
Some will take to C AND C++, some will take to only one
The majority are ok with python, some hate it

One of my long term projects is to take a type classification like
http://en.wikipedia.org/wiki/Myers-Briggs_Type_Indicator
and see how it maps to a person's potential as a programmer

Re: Debugging memory leaks

[writeson]

Dieter,

Thanks for the response, and you're correct, debugging memory leaks is tough! 
So far I haven't had much luck other than determining I have a leak. I've used 
objgraph to see that objects are being created that don't seem to get cleaned 
up. What I can't figure out so far is why, they are local variable objects that 
"should" get cleaned up when they go out scope.

Ah well, I'll keep pushing!
Thanks again,
Doug

SECOND TIME:

I'm not an apache wizard, and I'm too self important to really look through
all of your code.  i don't getting germs.  But, once again:

your code is not finding a file named this:
 '/home/nikos/public_html//home/dauwin/public_html/index.html'

The first part of this file path is:'/home/nikos/public_html

After that are TWO forward slashes which remind me of http:// and following
that is the path you want.  so, you need to put new batteries in your
brain, look through your mess and figure out what creates the wrong file
name for you

Re: Debugging memory leaks

[Dave Angel]

On 06/13/2013 02:07 PM, writeson wrote:

Dieter,

Thanks for the response, and you're correct, debugging memory leaks is tough! So far I 
haven't had much luck other than determining I have a leak. I've used objgraph to see 
that objects are being created that don't seem to get cleaned up. What I can't figure out 
so far is why, they are local variable objects that "should" get cleaned up 
when they go out scope.



Pure python code shouldn't have any leaks, but instead can have what I 
call stagnation.  That's data that's no longer useful, but the program 
has fooled the system into thinking it should hang onto it.


A leak happens in C code, when all the pointers to a given hunk of 
memory have gone away, and there's no way to access it any longer.


In pure Python, you don't work with pointers, but with references, and 
they are ref-counted.  When the count goes to zero, the object is freed. 
 Periodically a gc sweep happens, which catches those circular 
references which never actually go to zero.



So post a fragment of code that seems to cause the problem, and maybe 
someone can explain why.


1) objects with a __del__() method
2) objects that are "cached" by some mechanism
3) objects that collectively represent a lot of data
4) objects that are exposed to buggy C code

Re: My son wants me to teach him Python

[russ . pobox]

I couldn't read every post here so don't know if this has been suggested, or if 
there is perhaps a better suggestion which I haven't read in this thread, but 
in as far as I've read I feel the need to recommend:
learnpythonthehardway.org

Knowing a little JavaScript and even allot of HTML doesn't take him out of the 
total noob category when it comes to programming (did someone say game 
programming? Hold your horses!). I took a visual basic course (which I dropped 
out of admittedly after 3 months) and still knew absolutely nothing, which 
isn't necessarily just because I'm dumb.

After eventually learning Python in incremental and sporadic episodes of free 
time, I did come across a few resources and by virtue of the frustration of 
having taken so long to learn to code in the easiest damn programming language 
to learn, I found myself scrutinizing allot of the tutorials I'd been passing 
by.

I noticed developers.google.com somewhere up there. That's just a no no. Sorry. 
Maybe some of the people here are more than "pretty smart" but there's a good 
chance it'll be over his head at first, and at first is a bad place to be in 
over your head when you're learning the fundamentals.

I also notice Invent with python. I personally would go for 2.x rather than 3 
but that aside, for reasons I'm too tired to word, I didn't find it a good fit 
for me. I takes a "dive right in" approach and well, I never did learn to swim.

Udacity was the third suggestion I noticed. This is also a no no. I completed 
the cs101 udacity course which I'm sure is the course in question here, and I 
loved it! Really I learn crap load from it, but at every step I asked myself, 
would this had helped if it was the first place I went to to learn to code? No. 
There were allot of gaps I noticed when looking from a complete beginners 
perspective and even though the course claims to has no prerequisites, I would 
have hated if I started with that. However that was last year and I think it 
was only a few months old, so it may be allot different now, I haven't checked.

I read How to think like a computer scientist, A byte of python, and even the 
official docs. The only one I came across that made me say "&*#! why didn't I 
google that?" was learnpythonthehardway.

I do think it depends a great deal on the individual, and for me personally, 
that style of learning was just it. For one you learn from the bottom up. It's 
a compulsion for some to know that that know a thing before they're brave 
enough to move forward. In cases where a "leap" is the only way forward, the 
tutor pulls you across that divide by your ankles. You feel a sense of 
obligation to take to his instruction. And above all, it greatly emphasizes the 
"learn by doing" approach, in small steps, not big projects that you end up 
completing just to get through it but don't learn much from.

So that's my recommendation. But all that aside, my biggest point would be, 
just pick one do it. As you can see if you read that, my biggest flaw was 
simply the lack of devotion to one path.

Game programming if he still wants to do that is another question entirely I 
feel. Fundamentals are fundamentals. The only variable is how long it might 
take him to get passed it. Even with Python, some people just never get it.

Creating a Super Simple WWW Link, Copy, & Paste into Spreadsheet Program

[buford . lumbar]

Hi, I'm new to Python. Would someone be able to write me and/or to show me how 
to write a simple program that:

1-follows a hyperlink from MS Excel to the internet (one of many links like 
this, http://www.zipdatamaps.com/76180, for e.g.) and then,

2-copies some data (a population number, e.g. 54195) and then,

3-pastes that data back into the same MS Excel spreadsheet, into the adjacent 
cell.

... and that’s it... row after row of hyperlinks all in one column...

Please, please help me my wrist is starting to hurt a lot. You would have my 
greatest appreciation for your help!

thank you, Buford
