popen()? popen2()

Hello,
 
I need some help with popen().  I am calling a bash executable from a python program and it hangs; However if I run the bash program directly from the command line it works.  I don't know if has to do with popen() or should I use popen2().  I appreciate vey much any help that anyone can provide.

        else:
