Python Module for Determining CPU Freq. and Memory?

[efrat]

   Hello,

   I'd like to determine at runtime the computer's CPU frequency and 
memory.

Is there a module for these types of queries? platform.platform returns 
the computer's CPU name and type, but not its frequency; nor does it 
report how much memory the computer has. In the python help(), I 
searched for moudles cpu, but non were found.
(Please note: I'm interested in hardware stuff, like how much memory the 
machine has; not how much free memory is available.)

   Many Thanks,

   Efrat

Python CGI problem: correct result, but incorrect browser response.

[Sullivan WxPyQtKinter]

title:Python CGI problem: correct result, but incorrect browser
response.

In one of my CGI program,named 'login.py', the script return a HEADER
to web browser:

Set-Cookie: sessionID=LAABUQLUCZIQJTZDWTFE;
Set-Cookie: username=testuser;
Status:302
Location:edit.py
(blank line)

but the IE prompted to let me choose to save the 'login.py'. When I
save it, the file is just the header. That means the IE failed to parse
the header. My IE has already enabled cookie read and write. I also
tried Firefox, but the result is the same. How does this happen?

For Windows, you could use WMI. Something like this:


import wmi

c = wmi.WMI ()
for i in c.Win32_ComputerSystem ():
  print i.TotalPhysicalMemory

for i in c.Win32_Processor ():
  print i.DeviceID, i.MaxClockSpeed, "MHz"



You can get the wmi module from:

Handling IP addresses with SimpleXMLRPCServer.

[Jose Carlos Balderas Alberico]

Hello. I' m trying to use the client's IP address in a method defined inside the SimpleXMLRPCServer. Up till now I'm able to verify that the client's IP is an authorised one (I do this before calling the _dispatch method). I can redefine the _dispatch method extending the SimpleXMLRPCHandler class, and do something like 

 
if (self.client_address[0] not in [list of IPs])
    raise self.UnknownIP, "Unknown IP address"
 
else
 *inserts SimpleXMLRPCHandler's _dispatch code in here*
 
This works just fine, but I need to do something else. I need to have the IP address within the called method to know who's the client calling the method, and act in cosequence. There are 4 possible clients who will be requesting data from the server, and I need to check woh's actually requesting them via IP.

 
Is there any way to handle the client's IP inside a method in the server?
 
Thank you very much in advance for your help.
 
Jose Carlos.

For looking at memory on windows you might be able to make improvements 
to this class I wrote.  I was going to add memget() methods for getting 
individual items,  but it wasn't as useful as I was hoping it would be 
in checking my python memory use.  For that I need info on individual 
tasks, but this might be better for your use.

Cheers,

Both. Documentation for PyUnicode_DecodeUTF16 and PyUnicode_EncodeUTF16
is pretty clear when BOM is produced/removed. The only problem is that
you have to find out host endianess yourself. In python it's
sys.byteorder, in C you use hack like

unsigned long one = 1;
endianess = (*(char *) &one) == 0) ? 1 : -1;

And then pass endianess to PyUnicode_(De/En)codeUTF16. So I still don't
see what is unclear about BOM production/handling.

It would be surprising if it did. Quote from
: "Where the data is typed,
such as a field in a database, a BOM is unnecessary"

It depends on whether user entered url into address bar or clicked on
submit button on a page. In the first case there were no standard how
to deal with non-ascii characters for a long time. Only rfc 3986 in
2005 said: use utf-8. In the second case browsers submit forms in the
encoding of the page where the form is defined. Most likely that is
what you see when you capture traffic.

I guess it is because web pages usually serve pretty closed language
communities. Some people just encode urls as latin-1, and it works for
99.% of their users. They just don't care that they don't handle
chinese characters since they have no chinese users.

It is not clear what you do. Are you interacting with independant 3rd
party web service or you control both server and client?

Seems mostly clean. +1.

(and I do prefer it with the 'create' statement - more explicit and

debug CGI with complex forms

[Sullivan WxPyQtKinter]

When the form in one HTML is very complex with a lot of fields(input,

burdernsome, so I usually change the stdout and stderr of the submit

Well 3 * D(6) is similar to the notation used in roleplaying,

I have to look it up myself regularly. But in this case
it was more a matter of some intuition that 3 * D(6)
was not the same as D(6) * 3. You may have a different
intuition.

malloc'ed PyTypeObject

[Gabriel de Dietrich]

  Hi,

  I'm doing my first project on embedding and then extending Python in
an application. The idea is to import a set of C++ plug-ins into Python
and then be able to run a script that uses these plug-ins. Please note
that what I'm importing into Python are the plug-in classes in order to
be able to instanciate as many objects as needed.

  As usual, all the plug-ins derive from a base class. But two
important things differ for each plug-in, its name and a set of
parameters.

  For instance, the C++ class

class SNRFilter : public BaseFilter
{
   ...
};

can be instanciated in a Python script as

snr = SNRFilter()

  (This is a quite simplified example as there is also a quite trivial
SNRFilterClass class deriving fron BaseFilterClass. But those are
implementation details).

  So, everything works OK, but there will probably be a memory issue.
Each time I add a plug-in class into Python, I malloc a PyTypeObject
and copy its contents from a template static PyTypeObject. Then I
malloc and assign its tp_name and its tp_getset (array of PyGetSetDef).

  Now the question is, how can I be sure that all this memory will be
properly free'd after calling Py_Finalize()? Is it enough to add
Py_TPFLAGS_HEAPTYPE? Can I safely free tp_getset after calling
PyType_Ready()? What will the weather be for the next week-end?

  Thank you for reading.

It is interesting that the support for full continuations was removed
in recent
versions of Stackless (I think there was support in version 1, not in
versions
2 and 3, but I am not a Stackless user so please correct me if I am
wrong).

Coroutines give you more control on your program flow, but not as much
as
full continuations. With full continuations you can store the current
state
of your program (with some restrictions, the program should not have
side effects or interact with an external environment) and at a later
time
go back to to that state. In a sense you can go back in time (but only
in
points that your program has already travelled) whereas with coroutine
you can go just in one direction in the time. A nice thing you can do
with full continuations is a modal Web server
(seehttp://www.double.co.nz/scheme/modal-web-server.html).
But this is definitely OT for this thread, so let me stop here ;)

work and same code working properly here! (returning %B1) I'm not sure
and not checked yet but locale settings and/or installed Python version
may be different between two computers.

I think there should be way to encode ± to %B1 on any platform/locale
combination. While searching for a real solution, I'm going to add a

Because my queries are constant and %C2 is the only problem for now.

you can replace sys.stdout (and/or sys.stderr) with your own file-like
object, e.g.

class NullStream:
def write(self, text):
pass

import sys
sys.stdout = NullStream()

if this doesn't solve your problem, you have to be a bit more specific
(since in general, python doesn't print anything unless you ask it to...)

hope this helps!

Simple string formatting question

[Steven D'Aprano]

I have a sinking feeling I'm missing something really, 
really simple.

I'm looking for a format string similar to '%.3f' 
except that trailing zeroes are not included.

To give some examples:

FloatString
1.0  1
1.1  1.1
12.1234  12.123
12.0001  12

and similar.

Here is a (quick and dirty) reference implementation:

def format(f, width=3):
 fs = '%%.%df' % width
 s = fs % f
 return s.rstrip('0').rstrip('.')


Is there a way of getting the same result with just a 
single string format expression?

Converting Integer to String

The repr function inserts a '\n' at the end of the string, and I need to get the string representation without the '\n', since I need to insert the stringed data into a sql query.
 
I get "SELECT * FROM blah WHERE(code = 23\n)"
 
I need to get rid of that "\n". Is there any other function I can use to turn an integer into a string without the \n at the end?

Thank you for the quick reply, but still doesn't work. Now it seems the "\n" is executed instead of printed.
 
This is what I get when I print the query:

The code is being executed in an XMLRPC server. Maybe that's the problem? I don't know, but I don't get the \n when I execute str or repr in the python command shell.

I'm obviously missing some context here, but "encoding ± to %B1 on any
platform" is exactly what urlencode does:

>>> import urllib
>>> urllib.urlencode([("key", chr(0xb1))])
'key=%B1'

(however, if you pass in unicode values with non-ascii characters, url-
encode will give you an error).

are you sure the conversion to UTF-8 isn't happening *before* you pass
your data to urlencode ?  what does

print "1", repr(data)
print "2", repr(urllib.urlencode(data))

print for the kind of data you're encoding ?

But be warned, I've had difficulty restoring stdout 
afterwards, and needed to exit the interactive

Because I'm paranoid, I might prefer to leave
sys.stdout as it, and use a custom print
function which I control:

_CAPTURE = StringIO.StringIO()
_FLAG = True  # start capturing

def print(obj):
 global _CAPTURE, _FLAG
 if _FLAG:
 where = _CAPTURE
 else:
 where = sys.stdout
 print >>where, obj

Then I can start or stop capturing printing just by 
changing a flag.

you can print directly to a log file:

mylogfile = open("logfile.txt", "a")

print >>mylogfile, "my log message"

or you can replace sys.stdout (and/or sys.stderr) with the log file object:

import sys

Using PythonWin32 to copy text to Windoze Clipboard for Unix-style random .sig rotator?

[dananrg]

Can you tell I miss Unix?

I want to write a Python script that, when launched, will choose a
random .sig (from a list of about 30 cool ones I've devised), and store
the .sig text in the Windows Clipboard, so I can then paste it into any
Windows application.

This way, it'll work for Outlook e-mails, Yahoo, Gmail, etc.

Also, could I use Python to programmatically set key combos to do
certain things?

Should I buy the Python on Win32 book? Are all my answers there? Or is
there a good PyWin32 FAQ where all (that I'm interested in with this
particular e-mail) will be revealed?

Spammity-spam, y'all.

Thanks.

I suggest you remove the print statements and start using the logging
module instead. It's much more powerful, and allows you to put debug
statements in a file, for instance.

How to work with directories and files with spaces

[s99999999s2003]

hi

I am working in unix and i have some directories names with spaces
eg ABC DEF A
how can i work effectively with spaces in directory/file names in
python?

sometimes when i do os.path.join(dir_with_spaces,"-somestring" ) , it
gives me "-somestring"  as the name only...without ABC DEF A
it should give me ABC DEF A-somestring as the directory name

thanks

since most Python distributions comes with Tkinter, you can use Tkinter's
clipboard interface.  unfortunately (at least for this use case), Tkinter re-
moves things it has added to the clipboard when the program terminates,
so you have to make sure that the program is still running when you need
the text.

here's a fortune generator that keeps posting important stuff to the clip-
board at random intervals:

import Tkinter
import random, time

# get some phrases
import StringIO, sys
stdout = sys.stdout
try:
sys.stdout = StringIO.StringIO()
import this
FORTUNES = sys.stdout.getvalue().split("\n")[2:]
finally:
sys.stdout = stdout

# create an invisible (well, not really) window
root = Tkinter.Tk()
root.withdraw()

def refresh():
fortune = random.choice(FORTUNES)
root.clipboard_clear()
root.clipboard_append(fortune)
root.after(random.randint(100, 1000), refresh)

refresh()

root.mainloop()

(since this will make it impossible to use the clipboard for anything else, you
might wish to use a button instead of a timer to update the clipboard...)

You might try looking into wxPython.wx.wxTheClipboard

However, unless this is soley for your own use, I would suggest you try a
different method. In my experience, users get annoyed when their clipboard
contents are stepped on.

One general, if messy, solution is to use pywinauto to type the text in
directly. 

Another (much more ambitious) project would be to create a private clipboard,
save the current clipboard contents there, and then swap them back in when
you are done.

Ryan

os.path.join joins paths with the proper OS-dependend separator. So 

os.path.join("a", "b", "c")

becomes

a/b/c

under unix.  Naturally, joining dir and "-dummy" produces "/-dummy" -
which is what you see. 

Instead, do something like this:

for d in os.walk(rootdir):
 (dirpath, dirnames, filenames) = d
 for dir in [dirpath]:
 fname = os.path.basename(dir) + "-dummy"
 if not os.path.exists( os.path.join(dir,fname) ):
 f = open( os.path.join(dir,fname) ,
 "w").write("")

os.path.join joins path elements, so that's entirely expected.

try

filename = dirpath + "-dummy"
if not os.path.isfile(filename):
open(filename, "w").close()

instead.  or if you want to "touch" the file even if it already exists,
just do

open(dirpath + "-dummy", "w").close()

(to only touch a file if it exists, you can use os.utime(filename, None)
instead)

Cleaning the current environment after a fork

[Robin Haswell]

Hey guys

I want to fork a process, but my scope has lots of stuff that the child
won't need. Is it possible to clean the current environment of cruft so it
is collected and freed? Basically I want it to go something like this.
This is my first forking Python app, by the way:

# {{{ My app

import lots, of, stuff

# ...snip...

ret = os.fork()

if ret is not 0:

# clean my environment of lots, of, stuff so they are collected and
# memory is freed

import mymodule
worker = mymodule.MyClass(**kw) # some arguments that I have worked out
worker.Go()
sys.exit()._exit()

# carry on

# }}}

Obviously I only want to selectively clean the environment. I was thinking
something along the lines of:

tokeep = ["kw", "others"]
for obj in dir():
if obj not in tokeep:
delattr(?, obj)

However I can't access the local scope with (del|get|set|has)attr.. can I?

I would like to do it this way instead of os.popen() because there are
structures I'd like my child to have which would be tricky to pass through
shell args. 

Any help would be appreciated :-)

Thanks

Thanks for the information!

One question: Is there a safe way to keep extension modules backward- 
compatible with older Python versions? I am thinking of something like

#ifndef PY_SSIZE_T_DEFINED
typedef Py_ssize_t int;
#endif

assuming that Python 2.5 defines PY_SSIZE_T_DEFINED.

I'm not an expert of this - but if all the reason you want to do this are
memory concerns, AFAIK forking will only make a copy of those memory-pages
that are actually written to by the forked process - for efficiency
reasons.

And even if that wasn't the case: I think as long as you don't run into
memory-troubles, don't do it. Its complex, flaky and thus an unnecessary
source of failure.

I don't think raw_input decodes non-ascii input at all. and your console
probably uses cp850 rather than cp1252.  doing the comparision over in
unicode space should work better:

import sys
text1 = u'españa'
text2 = unicode(raw_input(), sys.stdin.encoding)
if text1 == text2:
print 'same'
else:
print 'not same'

How to change the docs - a case study

[Kent Johnson]

There has been a lot of discussion here recently about making changes to 
the docs, and what new system should be in place, etc., wiki, etc. I 
occasionally chime in with a note that it's pretty easy to submit a doc 
patch through SourceForge and they are often accepted quickly. The point 
being that there is a system in place that in my experience works pretty 
well.

Here is an example. This morning I noticed a minor discrepancy in the 
docs for the 'rot13' encoding. I posted a bug to SourceForge at 10:05 
GMT. At 10:59 someone commented that maybe the code was broken rather 
than the docs. At 11:18 another poster responded that the code should 
stay the same. At 11:25, less than two hours after my original report, a 
fixed was checked in.

The complete exchange is here:

This works assuming all line elements are quoted.

This would fail if (and this too my knowledge is proper CSV):

"Col 1 data 2,000", Col 2 data 3000, "Col 3 data 4,000"

Since the second element doesn't have a comma, it doesn't have to be  
quoted.

It's probably best to use the built in CSV parser assuming your data  
conforms to
the basic rules of CSV files.

shelve and ".bak .dat .dir" files

[Michele Petrazzo]

Hi,
I'm trying a script on a debian 3.1 that has problems on shelve library.
The same script work well on a fedora 2 and I don't know why it create 
this problem on debian:

#extract from my code
import shelve
class XX:
   def __init__(self):
 self._data = shelve.open("/tmp/myfile")

   # do the work

   def onClose(self):
 self._data.close()


Now I see that shelve create not my file, but three files that has the 
name that I want (/tmp/myfile) and also the extensions: .bak .dat .dir

Of course, before say to shelve to open, I delete the previous file, and 
I have all the rights to do what I want into the directory.

How solve it?

Can;t be done, to my knowledge. You specify a particular precision,
and the number will be formatted at that precision. This matches the
'printf' behaviour that inspired string formatting operations.

If your brute-force approach works, stick to that until you have a
reason to look for something better.

Why couldn't you? Maybe I'm not reading carefully enough, but I didn't

Yeah, how about we read your mind or make wild guesses about why it's

Really, your response seems a little bizarre to me, given that __float__

float() is what the % operator calls when it encounters a '%f' in the

+1 from me on this one.

Something it could be useful to try to add, if possible: So far, it
seems that this create block can only create class-like things (objects
with a name, potentially bases, and a namespace). Is there a natural way
to extend this to other things, so that function creation can be
modified? For example:

create tracer fib(x):
# Return appropriate data here
pass

tracer could create a function that logs its entry and exit; behavior
could be modifiable at run time so that tracer can go away into oblivion.

Given the current semantics of create, this wouldn't work. What would be
 reasonable syntax and semantics to make something like this possible?

Maybe this would need to be a separate PEP. But it seems at least
somewhat related.

I used to use pickles a lot for making scripts start up faster by cacheing 
intermediate results.  On startup, I had to read and parse a bunch of large 
text files and build a complicated in-memory database out of them.  That 
took something like 10 seconds.  However, the text files very rarely 
changed.  To save startup time, I read the files in once, and pickled the 
database in a file.  On subsequent runs, I'd just read in the pickle, which 
took a fraction of a second.

Ooops, don't combine the two calls to rstrip().

def format(f, width=3): return ("%.*f" % (width, f)).rstrip(".0")

print format(3.140)
print format(3.000)
print format(3.001)
print format(30.)
print format(30.000)

Gives:
3.14
3

But this works fine:
def format(f, width=3): return ("%.*f" % (width, f)).rstrip("0").rstrip(".")

BIOCHIP --->>> NO GOOD !!

[okay]

Hello,


http://www.av1611.org/666/biochip.html

To Archbishop Christodoulos Paraskevaides of the Greek Orthodox Church
in Athens and Greece
Archbishop,
I talked with a Greek Orthodox believer in Australia and he told me two

things of interest in these last days, as we see it this day even.

They had a large group of personnel from America come to Australia to
set the same kind of situation there as in America, getting set to
gather up all that will resist taking of this biochip implant which is
the
mark of their beast name and number in it, as well as all the
information about you held in the computer beast Belgium center. They
have also
taken all the weapons of self defense away from all the people of
Australia so that only these U.N. "peacekeepers" have weapons
together with
the new world order police.

It is going on in America too. Little by little, they are going to take

all the weapons of self defense away from Americans so there will be no

one to resist the dictatorship takeover by adolf george bush as liken
to a modern day adolf hitler. And just as adolf hitler was, so is
george
busha member of the satanic "skull and bones" society. His guide
book
is hitler's Mein Kampf.

These new world order people are in every capital in high places as
written, Ephesians 6:12, and are they that do II Corinthians 11:14 to
15.
First, they started by putting a biochip in every stray dog. And now,
every item you buy at the supermarket will have a biochip in it. And
they are set to implant all the military in America with this biochip
implant mark of their beast. Then Australia, New Zealand and then to
all of
Europe. It will come very quickly before the son of perdition is
revealed soon to take charge of this new world order of antichrist
people.

There will be no neutral country to flee to, as all nations are being
taken over. And their spy satellites can check all people, those that
have this biochip implant and those that do not, so as to send their
gestapo police to gather all who have not the biochip implant and take
them
to prisons to torture people so as to force them to accept this biochip

implant mark of their beast with his name and number in it.

Archbishop, Jesus warned us through His words given by His real prophet

of this time, liken to Daniel 12:1 to 4 and Matthew 24:37 to 41, only
that He will redeem you off this evil corrupt earth full of rebellious
people. Soon will anyone really make it to where He is and all the real

saints await you, Revelation 6:9 to 11.

Brethren in Christ Jesus' Name,

I do believe the Lord has to save Americans from the real trouble to
come soon. Daniel 12:1-2. Bush has taken all the military out of
America. Now all there is, hidden all over America, Chinese, Russian,
German and other supposed to be U.N. "peacekeepers", which are not
there for that purpose. Bush is gathering more German soldiers to
protect the U.S. military bases. He says.

Did you know they have big prisons made from used-to-be military
bases, now to be used to gather all the persons on adolf bush's Blue
list of people who will oppose his tyrannical takeover of America
when he creates a situation to call upon Marshall law and simply
takes over America soon.

And all that will not accept his smallpox inoculation and biochip
implant with the mark name and number of their beast as per
Revelation 13:16-18, will be placed into one of these 107,000 big
white boxcars with shackles to take them to a termination building
where they end up as a pile of ash, to hide whatever happened to
them. And it all is done through good old "christian" bush's
direction.

He is not a Christian, but a son of the devil, as most of the U.S.
government who are also illuminati satanists.

When bush places the mark into the people all over America, then the
vision I saw in Athens, Greece, can come to pass. Down she goes. Only
the very elect chosen few will the Lord gather out of it who are
accounted worthy to be chosen of Him. His very elect chosen and
faithful, Mark 13:20 + 22 + 27, to be quickened by the Holy Spirit
alive in them as wise virgins written in Matthew 25:1 to 12. His true
bride to be taken, Revelation 12:14.
Revelation 22:11-12.

help with designing an app. based on ConfigParser

[Alexandre CONRAD]

Hello list !

I'm using the ConfigParser module to use configuration files (what else 
would it be for ?). But I have a dilema: I'd like to setup multiple 
"update server" for my application with update "priority".

At first, I thought about adding a new section in my actual existing 
config file such as:

   [UPDATE SERVERS]

and have options like that:

   server10 = ftp://user:[EMAIL PROTECTED]/remote/dir
   server20 = ftp://user:[EMAIL PROTECTED]/remote/dir

That way, I would simply parse all servers in the "UPDATE SERVERS" 
section and sort them so I could get the priority (lowest number is 
higgest prio).

But, with this option, I don't know how to download files to a specific 
local directory. Then I thought about adding some "local10", "local20" 
options that would have the same number as the server, but ... baah, it 
starts beeing a pain when you want to maintain and update the server 
list. Also I would like to set multiple kind of update servers, like 
http, rsync, having to parse split up the URL is also a pain.

So instead of having all the data in a URL and having to parse it, I 
thought I might specify an option for each params and then build the 
needed URL. Like

   proto = ftp
   ip = 0.0.0.0
   port = 21
   remote_dir = /remote/dir

And I could add extra info that would make my life simplier that I 
couldn't have in the URL:

   enable = True
   priority = 15
   local_dir = /local/dir
   args = ""

That way, if I need to do an rsync, I can look for specific rsync 
options if available.

But now, how do I hold multiple servers ? In this case, I thought about 
having multiple sections such as

   [SERVER 01]
   [SERVER 02]
   [SERVER 03]

But it's not very efficient when I want to parse the WHOLE config file 
to find which servers are available and retrive their options. (plus, 
"01", "02", "03" would be useless, just for anti-conflict section naming)

if section.startswith("SERVER"):
 ...

So I told my self, the best way would be able to have a "sub-section". I 
could then look for all servers (aka sub-sections) inside [UPDATE 
SERVERS] and retrieve the needed info. But AFAIK, it's not possible 
having sub-sections with ConfigParser. So I'm here to ask if anyone has 
an efficient trick for that ? Maybe an other module based on 
ConfigParser exists that would allow sub-sections ?

I might be looking for something too complicated and maybe some simplier 
alternative exists which doesn't cross my mind right now. (no, don't 
tell me to use XML for my config file, it has to be easely modifiable by 
the user using the most basic bloc-note).

If you had difficulty, perhaps knowing about sys.__stdout__ would have 
helped... (?)  There's no need to preserve the original sys.stdout as 
you do above (in simple scripts, anyway) since Python does it for you. 
(Yes, in a library routine such as unittest you might need to do it in 
case the calling code has already modified it, but I doubt that's 
relevant in the OP's case.)

It took a few minutes of my time. Maybe a minute to verify that there 
was no similar bug report, a few minutes to write up my findings and

My understanding is that there is a build step required. So the change

No, I didn't say that at all. You are welcome to spend your time as you

GUI issues in Python

[diffuser78]

Hi,

I want to create a GUI where a user can select drag and drop kind of
boxes, circles and make connections between them.

This is basically for depicting states and dependencies. I am writing a
program where I let the user input states and dependencies in a certain
domain. Based on input given by user in the GUI, I grab it and run my

I am wondering if there is any library like that in Python, or if
anybody of you has done something similar in past, could you post some
pointers.

I'm just discovered that I don't have to remove that line, just change

ConfigParser will read the entire file in any case, so I'm not sure why sorting 
the
entries by server rather than by parameter would make things less efficient...

fwiw, I'd probably use

[server ]

where  can be chosen freely by the user, as long as it's unique.  e.g.

[server server10]
param = ...

[server dinsdale.foo.org]
param = ...

[server nisse]
param = ...

but I'm the kind of programmer that prefer to keep things simple, so I'm sure 
you
can find more complicated ways to do things ;-)

tkinter. Amongst a bazillion others - but this is included, and the
canvas-widget actually very useful for your purpose.

This is a documented behaviour of shelve:

http://docs.python.org/lib/module-shelve.html

and note "an extension may be added to the filename and more than one
file may be created". I guess this depends on what dbm shelve is
built on the documentation implies it goes through anydbm. I'm not
seeing this behaviour on my Debian 3.1 (and I fail to understand why
it is a problem).

You can also use the HTML parser from libxml2 or any of the available

This is a very relevant question. I would expect the new keyword would
break lots
of modules. However measuring is better than speculating.

$ echo count_name.py

"Count the occurrences of a Python name in a script"
counter = 0
for tok_code, tok_value, (srow, scol), (erow, ecol), line in \
tokenize.generate_tokens(file(script).readline):
if tok_code == token.NAME and tok_value == name:
counter += 1
print 'line %s: %s' %(srow, line),
if counter: print '*** %s ***\n' % script
return counter

if __name__ == '__main__':
name = sys.argv[1]
scripts = sys.argv[2:]
total = sum(count_name(name, script) for script in scripts)
print 'Found %d occurrences of %r' % (total, name)

Here is the output on my box:

Re: GUI issues in Python

[diffuser78]

My question basically revolves around... that I dont want to draw
circles and boxes for drawing purposes.

I want the end user to be able to draw the GUI boxes and circles and
makes connection to depict states and dependencies. So its a little
unconventional and more like a SIMULATION TOOL.

I am pretty sure Python must have something like this. Any idea how to
go about it.

now to push lisp-style to the extreme, a recursive one-liner solution 
with presumably better stack behavior (assuming proper tail-recursion 
elimination, which I doubt is the case in Python).

Python 2.5a1 (r25a1:43589, Apr  5 2006, 10:36:43) [MSC v.1310 32 bit 
(Intel)] on win32
...

>>> cnt_ss(s,ss,s.find(ss,p+1),n+1)
>>> cnt_ss("AABBAAABABAAA","AA")
5
>>> cnt_ss("foolish","bar")
0
>>> cnt_ss("banana split","ana")
2

note though that the first solution beats this one on token count: 37 vs 42

some afterthoughts:

- look at Oreilly's "OS X Tiger for Unix Geeks" before you do anything
that'll break OS X.  Just in case you get the idea to upgrade the perl
that OS X installed, don't remove the one in /usr/bin either.

- investigate the Activestate disk image for OS X/Intel.  I say
"investigate" cause i don't have any experience with OS X/Intel, but
the Activestate releases i've used for Windows and OS X in the past
have all been very high quality.

python411 podcast -- problem with the 'modules' podcast?

[John Salerno]

Not sure if you guys follow along with the podcast, but if you do, has 
anyone else had problems listening to the Modules podcast? On my iPod, 
it stops at 8 minutes, and in iTunes it stretches out across the full 
17-19 minutes, but the contents are still just the first 8 minutes 
(meaning that what you hear at minute 1 might be the same if you skip 
ahead to minute 3, for example).

I think this probably needs a separate PEP.  Function definitions are 
really very different from class definitions.  But feel free to write 
that PEP. ;)

John, I'll go back and look intoi this tonight on the Modules Podcast.
Sometimes, the problems are specific to a given user's equipmentn, and
I don't always know how to fix them, which is frustrating.  But, maybe
there is a problem I can fix with that podcast. I'll let you know
ton=ight after I get home form my day job ;-)).

If I have extra time this summer, maybe.  It'd be fun to write a PEP and
figure out how to add it in to Python.  But that will definitely have to
wait until *after* semester tests, if I can even get to it at all...

This works if I use the console but gives the following error if I use
IDLE:

text2 = unicode(raw_input(), sys.stdin.encoding)

my program code is run under winxp my actual code is equal above
and
when i past the code i  forgot the quote but in my code the quote is
