Hi,
Try os.walk().
Don't remember the syntax right now, should be straightforward. Check
the standard Python docs that come with your Python installation. Or
start python and do:

import os
print os.walk.__doc__

And executing a system comand is os.system(...).

Caveat: there can be security risks with system(). Depends how you use
it and who you let use it with what arguments. Similar to risks with
CGI forms.
