How to use DDD for Python?

[Nicholas Lo]

Hi,

I have recently installed DDD 3.2.0 on my PC. As it is mentioned on the
DDD web site that it can be used to debug different languages using
different inferior debbugers. I have tried to use DDD with pdb.py as
follows but not work

ddd --pydb /usr/lib/python pdb.py

It prompts me that it requires an input file. I just wonder if anyone
can help. Do I need another inferior debugger instead?
