This method is only used by those who don't understand time
domain filtering.
It looks like the original poster was looking for something
that works with Python. Unfortunately I am not aware of
any time domain filtering or filter design modules for
Python. However, if the OP is willing to look a Octave:
http://www.octave.org/
it should be able to fulfill all his needs.
