I'm coming into this thread kinda late, so feel free to ignore...

... but Jorge is right.  This is easily picked up by a lint tool... and
good python programmers use them ;-).  Some python-aware editors even
have this functionality built in.

Using the above example:

        $ pylint who_no.py
        ...
        C:  1: Missing docstring
        C:  5: Comma not followed by a space
        for i in range(1,10000):
                        ^^
        E:  8: Undefined variable 'malformed'
        E:  8: Undefined variable 'beast'
