The os.popen(...) function will return a file like object, so you can
use a read() - method of these object to get the called programms output.
hope that helps - I' m very new to python
The documentation may be not well for all circumstances but the fine
thing is: the documentation is part of the code itself - inform of the
docstrings - and this is a very good approach. The bad thing is the
person who wrote the docstring was documenting his/her own code and not
code of other programmers.
