32 OS on 64-bit machine

[SamG]

If anyone has a x86_64 machine and is running a 32bit OS on top of
that could you tell me what output would you get for the following
program

#==
import platform
print platform.processor()
print platform.architecture()
#==

Thanks in advance

enable-shared

[SamG]

How we do if find that python that we are using is compiled with the --
enable-shared  option. There is can actually be done using 

distutils.sysconfig module but this modules is ported only with python-
devel but not with standard python install.

Is there another way apart from checking the pyconfig.h file.

Thanks in advance

This is only creating an out.log file and all the stdout and stderr
are logged there.

I have written this

import sys

class multicaster(object):
def __init__(self, filelist):
self.filelist = filelist

def write(self, str):
for f in self.filelist:
f.write(str)

log_file='out.log'
mc = multicaster([sys.stdout, sys.stderr, log_file])
sys.stdout = mc
sys.stderr = mc

print "Hello"

And i get this when i run the porgram.

HelloHelloTraceback (most recent call last):
Traceback (most recent call last):

Kindly advice!

Does not make difference, does this work for you? Im working on linux.
But this code looks portable except for the file path :)

Thanks people i have got it working now...

with this program!

#END
import sys

class multicaster(object):
def __init__(self, filelist):
self.filelist = filelist

def write(self, str):
for f in self.filelist:
f.write(str)

log_file=open('out.log','w')
mc = multicaster([sys.stderr, log_file])
sys.stdout = mc
sys.stderr = mc
sys.stdout.write( "Mojozoox\n")
sys.stderr.write( "Hello\n")
#END

works perfect for my needs.

Capturing the entry point of a script

[SamG]

If a function does not have main function defined and there is only a

if __name__="__main__":

how do i make a call to that using

profile.runcall( ...)

in my profiling script. Is there a way to find the entry point of a
script and indentify it with module method.

Then how do we check the value of the s's instance?

Crypto headaches.

[SamG]

Hi,

Using the python's Crypto.Cipher.Blowfish is create and encrypted file
in the CBC mode. Now... when try to decrypt it with OpenSSL i get an
error stating "bad magic number".

I tried
$ cat encr-file | openssl bf-cbc -d -pass pass:sam > org-file
or
$ openssl bf-cbc -d -pass pass:sam -in encr-file -out org-file

BTW, decryption using a python code works well. But i m of the
impression a file encry with one program should/can be decrypt with
another program (in my case openssl) using the same parameters.

Pls help.

Problem obtaining an object reference...

[SamG]

I have two windowing classes A and B.

Inside A's constructor i created an instance B to display its Modal
window. Only on clicking OK/ Closing this modal window do i proceed to
display the A's window.

All that is fine. Now the problem is i would like to write a python
script to test the this GUI app simulating all the events that make
A's window work through my script. No the problem is to get past my
B's window. Which i'm unable to do since the A's instance would any be
created completely if i click OK/Close button on the B's window. Im
unable to simulate that event since i have little idea about how to
get the object reference to B's window? Here is a sample of the code.


class Awindow:

def __init__(self):


self.showBwindow()
def showBwindow(self):
dialog = Bwindow()
dialog.ShowModal()
dialog.Destroy()

class Bwindow:
def __init__(self):



Pls help.

Why dont you try commands module instead

In [28]: import commands

In [29]: dir(commands)
Out[29]:
['__all__',
 '__builtins__',
 '__doc__',
 '__file__',
 '__name__',
 'getoutput',
 'getstatus',
 'getstatusoutput',
 'mk2arg',
 'mkarg']

In [30]: (a,b) = commands.getstatusoutput('whoami')

In [31]: print a
0

In [32]: print b

Threading and wx.....

[SamG]

Hi,

Im trying my hand at threading with wx applications. I have written
the following code...

import wx
from threading import Thread, Lock

class createWindow(Thread):
def __init__(self):
Thread.__init__(self)
self.lock = Lock()
self.app=None

def run(self):
#self.lock.acquire()
self.app = wx.PySimpleApp()
frame = wx.Frame(None, title="Hello wx")
frame.Show()
#self.lock.release()
self.app.MainLoop()


if __name__=='__main__':
c = createWindow()
c.start()
c.join()

Now when i run this program i get a window but the application just
does not respond. Is there something that im missing here. Pls let me
know. Thanks in advance.
