iterator idea

[Paul Rubin]

I wonder if Python would benefit from letting a generator jump to
another iterator, i.e. something like

   yield return *seq

would be the equivalent of

   for s in seq: yield s
   return

except that it would work by transferring control directly to seq's
iterator (like a goto) instead of calling it like a subroutine.  The
idea is to solve one of the perennial iterator annoyances, the
inability to push items back on an iterator.  For example, the
annoyance means itertools.takewhile consumes an extra element with no
reasonable way to retrieve it.  The new feature would let us write
something like (obviously untested):

  def takewhile_exact (pred, seq):
 """return two iterators (head,tail).  head is the same as
itertools.takewhile(pred,seq).  tail is the rest of the
elements of seq, with none missing.  You can't use tail
until you've iterated through head."""
 buf = []
 def head():
for s in seq:
   if pred(s): yield s
# save non-matching item so that tail can find it
buf.append(s)

 def tail():
if not buf:
   raise IndexError, "not yet ready"
yield buf.pop()
yield return *seq   # transfer control to seq

 return head(), tail()

The reason tail() can't just iterate through seq is that you
might call takewhile_exact many times:

   def is_even(n): return (n%2 == 0)
   def is_odd(n): return (n%2 != 0) 

   # we want to do something with all the runs of even numbers
   # in the sequence, and similarly with the odds.  seq is an 
   # infinite sequence.
   while True:
   evens, seq = takewhile_exact(is_even, seq)
   do_something_with (evens)
   odds, seq = takewhile_exact(is_odd, seq)
   do_something_else_with (odds)

Without the "goto"-like transfer, we'd get deeper and deeper in nested
iterators and eventually overflow the call stack.

inserting

 print sys.getrefcount(None)

at strategic locations in your code will usually help you identify the
culprit.

(last time I stumbled upon this was in an earlier release of "sqlite",
which leaked one Py_None every time you connected to the database.  our
application contained a separate task that created it's own database
connection every 15:th minute or so, to calculate some statistics.  and
a fresh Python interpreter contains 500-600 references to Py_None...)

The type of IPC required differs depending on who is using the shared region -
either another python process or another external program. Apart from the
spinlock primitives, other types of synchronization mechanisms are provided by
the OS. However, I do see value in providing a shared memory based spinlock
mechanism. These services can be built on top of the shared memory
infrastructure. I am not sure what kind or real world python applications use
it.

if you're going to post questions to arbitrarily chosen threads, you 
could at least change the subject (but it's a lot nicer to open a new 
thread).

the "**" prefix tells Python to stuff any excess keyword arguments into 
the given variable:

 >>> def func(**kwargs):
... print kwargs
...
 >>> func()
{}
 >>> func(spam=1, egg=2)
{'egg': 2, 'spam': 1}

for more on Python's parameter syntax, see the section on "def" in the 
language reference; see e.g.

 http://effbot.org/pyref/def.htm

Even that can probably be avoided since the mmap region has to start
on a page boundary, but anyway regular I/O definitely has to copy the
data.  For mmap, I'm thinking mostly of the case where the entire file
is paged in through most of the program's execution though.  That
obviously wouldn't apply to every application.

I mean just have an interface to OS locks (Linux futex and whatever
the Windows counterpart is) and maybe also a utility function to do a
compare-and-swap in user space.

Problem Commenting within Filehandle Iteration

[Wijaya Edward]

Hi all,
 
I have the following code:
 
 
import sys   
import re

ham_count = 0
spam_count = 0
myfile = open('full/index')
for line in myfile.readlines():
p = re.compile('ham')
m = p.match(line)
if m:
print line,
else:
#print 'SPAM -- %s' % line
myfile.close()

Sometime while developing/debugging the code we usually 
put in such situation. Where expression under "else"
is not yet supplied, yet we would like see the printout of the
previous "if" condition. 
 
Notice that I wanted to comment out the #print line there.
However I found problem with myfile.close(), with identation error.
This error doesn't occur when commenting (#) is not in use.
 
Why so?  Is there away to do the commenting in correct way
under this circumstances?

You're probably going to need to time that for your particular data. 
Here's what it looks like on an artificial data set:

$ python -m timeit -s "A = range(100); B = range(40, 60, 2); B_set = 
set(B)" "A = B + list(x for x in A if x not in B_set)"
1 loops, best of 3: 54.5 usec per loop

$ python -m timeit -s "A = range(100); B = range(40, 60, 2); B_set = 
set(B)" "A.sort(key=B_set.__contains__, reverse=True)"
1 loops, best of 3: 39.7 usec per loop

That said, I'd probably still use the first solution -- it's more 
immediately obvious why that one works.

Wait a minute, the first example looks wrong, B has gotten replaced by
a set and then it's added to a list.

Anyway how about timing

   C = set(A) - set(B)
   A = B + filter(C.__contains__, A)

This scans A twice, but it does more of the work in native code,
without sorting.

Slightly OT: Is pyhelp.cgi documentation search broken?

[Joel Hedlund]

Hi!

For a number of days I haven't been able to search the online python 
docs at:

http://starship.python.net/crew/theller/pyhelp.cgi

that is the "search the docs with" link at this page:

http://www.python.org/doc/

Instead of the search engine, I get Error 404. This is a real bother for 
me, since I rely heavily on it for my work.

Is it broken? If so, is anybody trying to get it back up again, and 
what's the time scale in that case? Is there an alternative available 
somewhere?

There's no maybe about it.  http://python.org/sf/1544277
There were also problems with the global statement and something with
keyword args.  Though, both of those may have been fixed.  Georg would
probably remember, I think he fixed at least one of them.

It's definitely broken unless someone fixed it when I wasn't looking.

I agree with Martin, a new maintainer would be nice.  I plan to look at

statement suites cannot be empty in Python (and comments don't count). 
to fix this, insert a "pass" statement:

 if m:
 print line,
 else:
 pass # print 'SPAM -- %s' % line

also see:

There has to be code in the ``else`` block.  So either comment out the
``else`` line too, or insert a ``pass`` statement.

Simple answer:

My preferred answer:

if m:
print line,

and get the lines back again later from your version control system.

That didn't seem to me to be a debugging statement being disabled, but

Make alternative like NAnt, rake, ... written in python?

[Achim Domma]

Hi,

I'm looking for a tool to automate build tasks like copying files, 
zipping them up, change config files  NAnt works fine, because it's 
quite easy to extend in C#, but it would even easier to write tasks in 
Python.

SCons is the only Python tool of this kind which I know. But SCons is 
much to complicated and not easy to extend. Rake looks very nice, but is 
written in Ruby. Is there something similar in Python?

Get coordinates of a cell

[Teja]

I have a GUI application with a Frame and a grid in it. I want to popup
a menu after the user enters some text in a cell and hits ENTER key. I
was able to popup the menu. However the menu is not popping up exactly
at the position where I want it. It should be popped up immediately
after the cell in which the user has entered the text. To get the co
ordinates I am using the function event.GetPosition(). Here event is
wx.EVT_KEY_DOWN. Any pointers please?

You were on the right track, but the built-in getattr is a perfectly
good argument to reduce(), using operator.attrgetter just makes the
definition more complicated (see my other post).

Ben,
 
I mean while opening a file, like this

for line in open('somefile.txt'):
print line

printing "line" will not show the hidden chars like "\n","\r".
Is there  a way to print it out?

Hey!

The task is:

"Remove the first two lines that don't begin with "@" from a file."


Actually, the grep-thing I offered will also delete copies of these two
lines that occur in another place. That should be no problem if the file
is something like

@comment
deleteme
deleteme
@comment
data: x-y-dy

However, if this is not the case, it cannot be done this way.
How would you do it with sed?

Best,
Sebastian.

Again, I don't know what result you want to see. The characters are
non-printable; what output do you expect?

If you want to see a Python string representation of the input, maybe
the 'repr' function is what you want.

>>> foo = "bar\tbaz\r\n"
>>> print foo
bar baz

>>> print repr(foo)
'bar\tbaz\r\n'

Just escape the '\' character. So you would do:

The Waf build system might be something to consider:

There is code for spinlocks, but it allocates the lockword in the process
memory. This can be used for thread synchronization, but not for IPC with
external python or non-python processes.
I found a PyIPC IPC package that seems to provide interface to Sys V shared

Cards deck problem

[Arun Nair]

Can any one help me with this im not getting it even after reading
books because there is not much of discussion anywhere

a>
 Implement a calss that represents a playing card.  The class should
implement the following methods:
_ _ init _ _ (self, rank, suit) Creates a card.
rank is an integer in range of 1 to 13 (Ace:1, King 13), suit is a
character in set {'h','d','c','s'}
getRank(self) Returns the rank of the card
getSuit(self) Returns the suit of the card
BJValue(self) Returns the 'Blackjack Value' of the card (Ace:1, Face
card:10)
_ _ str _ _ (self) Returns a string naming the card. For example: 'Ace
of Spades'

Test your class by writing a 'test harness' that generates 'n' randomly
generated cards, where 'n' is supplied by the user.  Print out the
string associated with each card and it's 'Blackjack value'


b>
Extend the card class to display in a graphics window.  the new class
should support the following method: draw(self, win, center) Draws a
card in a window.
Use the extended class to display a hand of five random cards.


c> Write a program that creates a list of card objects as above and
print out the cards grouped by suit and in rank order in each suit.
the program should read the values for the list of cards from a file,
where each line in the file specifies a single card with the rank and
then the suit separated by a space. Hint: sort the list first by rank,
and then by suit.


d> Create a new class deck that represents a pack of 52 cards.  Which
supports the following methods:

_ _init_ _ (self) - Creates a deck of cards in standard order.
shuffle(self) - Randomizes the order of the cards
dealCard(self) - Returns a single card from the top of the deck, and
removes the card from the deck.
cardsLeft(self) - Returns the number of cards left in the deck.
Test your class by having it deal out a sequence of 'n' cards where 'n'
is a number input by the user.  The program should either print out the
cards, or display them in a window.

Your urgent and quick reply help will be appreciated the most.

As far as readability goes - most computer languages have a surface
syntax which is (by design) vaguely similiar to the syntax of a natural
language like English. Thus statements roughly correspond to sentences.
For example, you can see a subject-verb-object pattern in "x=3". Given
a genuinely boolean construct like x < 2, "if x < 2:" *sounds* right to
a human reader. Similarly, given a good boolean variable with a
descriptive name like "found", the fragment "if found:" sounds ok. But
- given a non-boolean variable like "product_name" -  writing "if
product_name:" sounds (to my ears) a little jarring - it sounds like a
sentence fragment. It's like saying "If Bob" - If Bob *what*? Goes to
the store? answers the telephone? Finish the damn thought! Now, if you
were to (from some strange reason) use "product_name" as if it were a
truth value then (to my ears) it would both make your intentions more
clear and sound less fragmentary if you could say "if product_name ==
True:". When you use "product_name" as the condition of an if statement
then in that context it is *functioning* as a truth value so (naively)
what could be wrong with comparing it to a truth value? I don't
advocate any change in Python here - just pointing out that the idea of
allowing "if s:" and "if s == True:" to be always equivalent in the
interest of readability isn't *that* strange. It doesn't constitute a
redefinition of readability.

As far as using non-booleans as conditions - I just think that if you
want a certain block of code to be executed only if, for example, a
list is non-empty, why not *say* so? I think "if my_list != []:" just
reads better than "if my_list:". I would think that my preferences
there mesh with "Explicit is better than implicit" but apparently not.

I'm just starting out with Python with most of my programming in recent
years being in various dialects of Visual Basic (which probably
explains a lot). What attracts me to Python so far is the cool slice
operations, the iterators, the libraries and the convience of
programming in a REPL environment. So far, the ability to use "cat" as
a part-time substitute for True just strikes me as a curiousity - but
maybe that will change with time.

Yes, but you're talking about *your* ears there. I was pointing out, as 
others have, that "if product_name" is such a deeply-ingrained Python 
idiom that you can use how natural it "sounds" to you as a measure of 
your progress in the language.

Maybe so, but that "rule" (and let's not forget that the zen is not 
actually a set of prescriptive rules but rather guidelines for the 
informed) is immediately preceded by the most important "rule" of all: 
"Beautiful is better than ugly". Nobody will shout at you (well, 
hopefully, not on this list they won't) for writing

   if my_list != []:
 ...

in your code, but if they have to incorporate it into their own they 
will almost certainly reduce it to

   if my_list:
 

It's just idiomatic in Python, the same way that "'Sup?" is idiomatic in 
English (or what passes for it nowadays ;-) but grates on those who 
aren't used to hearing it.

It probably will, but I wouldn't get too hung up on what's definitely a 
small point. Enjoy Python the way it is, and the way you are. You and 
Python will definitely come to an accommodation (and you will love the 
combination of discipline and freedom that it brings to programming 
style). Welcome to the language!

Avoid the from XXX import * idiom whenever possible. Better to
explicitely tell what you intend to use, and where it comes from.

=> and here you overwrite self.suit

You have to use different names for the effective values of rank and
suit for a given instance of Card than for the lists of possible values
(hint : usually, one uses plural forms for collections - so the list of
possible ranks should be named 'ranks').

Also, since these lists of possible values are common to all cards,
you'd better define them as class attributes (ie: define them in the
class statement block but outside the __init__() method), so they'll be
shared by all Card instances.


 While we're at it, I think that you inverted suits and ranks... Please
someone correct me if I'm wrong.


> self.BJ = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 10, 10, 10]

Idem, this is a list of possible blackjack values, not the effective BJ
value for a given instance.

This will return the whole list of BJ values, not the effective value
for the current Card instance

better to use raw_input() and validate/convert the user's inputs by
yourself.

of course. You're trying to use self.rank (which is now a list) as an
index to itself (dito for self.suit).

subprocess-how to suppress the stdout

[alf]

Hi,
I use subprocess to execute another program but need to suppress its stdout.

I can achieve it by using Popen(...,stdout=subprocess.PIPE,...) but 
wonder where the all stdout actually goes. Is it buffered (to eventually 
fill up)or just discarded?

Or there is a better solution ...

Thx, alf

displaying \n-less prompts in a pythonic way

[alf]

Hi,

I have a command line program which also does some interaction with the 
user using stdin and stdout.

My requirement is to print prompt so the user can answer in the same 
line. Unfortunately:

  print 'enter command:',


does not really work as the comma is carried over to the following lines 
and the indentation gets messed up.


I can use sys.stdout.write('enter command:') instead but kind of do not 
like sys.stdout.write mixed up with print's statements used to display 
other informations.


Is there a pythonic solution for the problem?

it ends up in a pipe buffer, yes.

/dev/null is your friend:

Popen(..., stdout=open("/dev/null", "w"), stderr=subprocess.STDOUT, ...)

because there's no one around to split them up for you.

after all, that's the whole point of running another program without going 
though the
shell: what you pass in ends up, as is, in the other program's argument array.

Yeah, write a function:

def prompt(label):
'''Prompts the user, returning the typed text'''

sys.stdout.write(label)
return sys.stdin.readline()

The online help states :

|b(reak) ([file:]lineno | function) [, condition]
|With a line number argument, set a break there in the current

|which must evaluate to true before the breakpoint is honored.

"(Pdb)" is the prompt, as you can see.

I was thinking the "condition" is anything python can digest .Therefore an 'if 
condition: code' should be accepted. Editing a BP with a condition like that 
is taken as good (perhaps there's no check on its validity)

What one finds is that the command-shell is self-inconsistant:

C:\temp>md foo
C:\temp>md foo\bar
C:\temp>cd foo/bar
C:\temp\foo\bar>cd ..
C:\temp\foo>cd ..
C:\temp>cd /foo/bar
C:\temp\foo\bar>cd \temp
C:\temp>md foo/baz
The syntax of the command is incorrect
C:\temp>echo dir > foo/bar/pip
C:\temp>echo dir > /foo/bar/pip
The system cannot find the path specified.
C:\temp>dir foo/bar
Parameter format not correct - "bar".
C:\temp>dir /b foo\bar
pip
C:\temp>type foo/bar/pip
The syntax of the command is incorrect.
C:\temp>type foo\bar\pip
dir
C:\temp>cmd < foo/bar/pip
[directory listing within a subshell]
C:\temp>cmd < /foo/bar/pip
The system cannot find the path specified.


The CD, MD, TYPE, ECHO and redirection are all shell-builtins, 
yet they seem to be conflictingly quasi-smart about forward slashes.

Sometimes leading slashes matter.  Sometimes they don't. 
Sometimes forward slashes are acceptable.  Sometimes they aren't. 
  All within the shell's built-in mechanisms.  Go figure.

Or use raw_input(), which was designed for such situations:

Who is this? Steve

I wouldn't agree that there is no way reasonable way to get the terminating 
value with takewhile, you just need another generator or two:

>>> def repeatable(iterator):
it = iter(iterator)
for v in it:
while (yield v):
yield None


>>> def takeparts(predicates, iterator):
iterator = repeatable(iterator)
while True:
for pred in predicates:
yield takewhile(pred, iterator)
iterator.send(True)


>>> for seq in takeparts([is_even, is_odd], [2,2,4,5,6,6,7]):
print list(seq)


[2, 2, 4]

[6, 6]

Not only do you need to define them, but it would probably be a good
idea to populate them. And BTW, () is a tuple, not a list (but tuples
are perfectly ok for this use case).

You can, but shouldn't.

Is the same as:

if True

because (10 > 5) evaluates as True.

Did you mean

if (10 > 5) == True == True

or 

if (10 > 5) == True == True == True

or even 

if (10 > 5) == True == True == True == True

I hope you see my point now.


> because (10 > 5) does evaluate to "True".

I think it is a good time to remind people of some extremely well-thought
out opposition to the introduction of bools to Python from Laura Creighton:

http://mail.python.org/pipermail/python-list/2002-April/095878.html

She lost the debate, Guido had the final word and Python now has bools.
Take particular note of her description of Python distinguishing between
Something ("cat", 4, [0, 1, 2] etc) and Nothing ("", 0, [] etc).

Yes, that's what I meant. I didn't want it to return *yet* until a value

You can become proficient enough for basic editing in about 20
minutes with the built-in tutorial.

Getting it to work seemlessly with Python code will take

[ANN] IronPython Community Edition r3

[Sanghyeon Seo]

This is the third release of IronPython Community Edition (IPCE).

Get it here.
http://sparcs.kaist.ac.kr/~tinuviel/download/IPCE-r3.zip

This release is also available on SourceForge mirrors near you.
http://sourceforge.net/projects/fepy

IPCE has a homepage. You can read about licenses and patches there.
There's also some new documentations like FePy Library Reference.
http://fepy.sourceforge.net/

Changes in this release:

* Latest and greatest!

Updated to IronPython 1.0.1.
Updated to CPython 2.4.4.
Compiled with Mono 1.1.18.

* Relicensed under the MIT license, for those who found previous
license terms (Do What The Fuck You Want To Public License) offensive,
or humor-impaired.

* New CPython-compatible wrappers.

zlib, using System.IO.Compression.
hashlib, using System.Security.Cryptography.
sqlite3, using generic DB-API module already developed.

hashlib and sqlite3 are modules new in CPython 2.5.

* Updated CPython-compatible wrappers.

Numerous updates to pyexpat. Previously, pyexpat.py was only intended
to run ElementTree. It is now compatible enough to run xml.dom and
xml.sax codes.

* Patches to Python standard library.

patch-stdlib-tarfile-null-terminated fixes (arguably) a bug.

patch-stdlib-httplib-disable-idna and patch-stdlib-xml-sax-import are
workarounds, but changes are minimal and make using httplib and
xml.sax much better on IronPython.

Debugging/Networking ?s.

[Michael B. Trausch]

I am having a little bit of trouble figuring out what to do about a
problem that I am having with the program I am working with.

I had it working yesterday, and up through till this morning.  I hadn't
thought about putting it in version control until now, so whatever it
was I did, I can't just hit a revert button... that'll teach me.  :-)

Anyway, it opens a socket, and is capable of fetching the first output
from it and displaying it in the TextCtrl that it is using.  It also
says that it is successfully sending what is typed, be it an alias for
something else, or a straight command that needs to be sent.  However,
after the initial text is received, it says that it doesn't receive anymore.

I would believe that, if I could duplicate it with a known working
program (such as telnet)... but, I can't.  The server that I am working
with is working perfectly fine -- e.g., it is replying just as it should
be.  However, it is also not detecting any problem with the socket,
either.  :-/

The code is at http://fd0man.theunixplace.org/Tmud.tar.gz and if someone
could give me some insight as to what I might be doing wrong in
PlayWindow.py, method CheckAndProcessGameOutput, that would be
wonderfully appreciated.  I am out of ideas, myself.  It never comes up
with error, and never says that the socket is ready, either (using
select.select()).

Beware that the code isn't likely to be very pretty -- I am not an
experienced programmer.  Even some of the ideas I got from the ANSI
thread are likely to look not so pretty, because I probably mangled a
lot of that, too, though, it *was* working.  The only thing that
irritates me is that the changes I have been working on today have all
been in the SendOut method in PlayWindow.py, which should have no
bearing on CheckAndProcessGameOutput, so I don't know what really caused
it to stop working.

Thanks in advance for any assistance!
