like in
$ python
>>import os
os.system("so urce .bashrc")
sh: source not found and stuff
256
? I get
$ python
>>import os
os.system("so urce .bashrc")
/... stuff printed by my .bashrc file .../
0
What happens if you do
>>import os
os.system("ba sh .bashrc")
instead?

It _might_ be that the shell it fires up is /bin/sh and this in turn is
not bash.
Anyway, it's better to use subprocess / Popen for this sort of operation.

There's no 'source' program; it's a shell builtin. Even if there was, it
almost certainly wouldn't do what you want. The .bashrc file is supposed
to contain settings applying to the current shell, and os.system() runs in
a subshell, so the settings will only affect that shell.
If you're doing this to set environment variables, try modifying os.environ
instead.

Hello,
One of the greatest feature of Python in my opinion is the way the
interpreter can be used to integrate a wide variety of
software packages by dynamically linking them. This approach has been
extremely successful for us so far but now I run
into a license nightmare.
Some the libraries we wrapped using SWIG are under GPL but the
applications we are distributing are not (mainly because

Hi there,
This is my first post over here and I hope someone can give me some
guidance.
I'm trying to embed Python into a Visual C++ 2008 application and I'm
getting linker problems. I've compiled a DLL of the Python source code
using the pythoncode VC++ project in the PCbuild folder of the source
download and this works 100% without any warnings etc. I've done this
in Debug and Release mode without any problems.

Hi,
I am tryiong to do something obviously trivial such as:
I have a c program called "tsys2list" that when it is ran it asks the user to give the value of "tcal" which is a variable. I want to call the "tsys2list" from within a pyrthon script lets call it "gamma.py" >>>but<<< I want to pass the value of "tcal" to th eprogram automatically and not by interacting with the keyboard.
How do I do that?
thanks i advance!
