Executing a C program from Python

[vishakha vaibhav]

Hi,
I am very new to python. I have my cgi script written in Python. My CGI script 
should call a C program and collect the value returned by this program and pass 
it to the browser.
 
Can anyone help me out in this. How can I execute the c program and collect the 
return value.
 
I tried,
import os
a=os.system("my-app")//my-app is the C program executable
print a
 
But the variable a prints 0 everytime. It should return a non-zero value as per 
my C program.  Is there any method to do what I need.
 
Regards,
vish

Re: list problem 4 newbie

[vaibhav]

Hi,
if u check the id's of a and b lists and also its elements, you will
obeserve that the id's of a and b have changed  but id's of their
elements have not changed.
 If you make a deep copy of the list a and then make your changes in
that list, it shud work.  this can be done using the copy module.

hope that helps,
vaibhav

>>> id(a)
-1208622388
>>> id(b)
-1208622324

>>> for el in a:
... print id(el)
...
-1208622836
-1208622708
-1208622772
-1208622420

>>> for el in b:
... print id(el)
...
-1208622836
-1208622708
-1208622772
-1208622420

>>> import copy
>>> c = copy.deepcopy(a)
>>> id(c)
-1208464564

>>> for el in c:
... print id(el)
...
-1208465172

Re: import woe

[vaibhav]

Hi bob,

1. decide the directory which will be your root folder containing foo
[/home/ROOT/foo/]

2. work out your directory structure relative to this root folder
 here it is ->ROOT->foo->car.py
   ->bar->far.py
   ->bar->jar.py

3. add __init__.py file inside each folder containing a list variable
__all__ with contents as the name of the directories and classes
so foo folder should contain a file called __init__.py which has the
following contents
__all__ = ['bar','car']
and bar folder should contain a file called __init__.py which has the
following contents
__all__ = ['far','jar']

4. add the root folder to your sys.path
so your jar.py file should have the  following entries
from sys import path
path.append('../../../ROOT')

note: i prefer relative paths or make paths using os.getcwd
combinations in such situations, which makes the class more flexible.
you can also do this step where u configure/initialize

5. then you can import the classes you want in jar.py

from foo import car
from foo.bar import far

pls mail if u dont get it working/any doubts.

What are new-style classes?

[Vaibhav]

I recently heard about 'new-style classes'. I am very sorry if this
sounds like a newbie question, but what are they? I checked the Python
Manual but did not find anything conclusive. Could someone please
enlighten me? Thanks!
