Remote Debugging for python.

[nkarkhan]

Newbie to python here..so bear with me.

I used to be able to gdb to a target machine running c/c++ code and
see where my program was hanging, crashing, executing..

How do I do that with python?
I have multi-threaded python programs running on a remote machine. I
want to se where they are at any instance.

If remote debugging is too much to ask for.. what about local
debugging?
Can i break into an executing program and see at source-level where my
pyhton program/process/thread is at?

Thank you,
Nitin.
