Debugging Python -Newbie?

[David Lees]

I am looking for an elementary introduction (cookbook) to debugging
Python code with either PythonWin or IDLE.  I am playing with the
classic recursive factorial example in PythonWin and somehow am not able
to single step through, even though I see the step functions (F11 and
F10).


A pointer to step by step instructions on debugging/debuggers would be
great.

Thanks in advance.
