You could save this in a file and execute it with "python -i file.py".

It seems to work here:

[niemeyer at ibook niemeyer]$ echo 'a = 1' > mod.py
>>> import mod
>>> mod.a
1

[niemeyer at ibook niemeyer]$ echo 'a = 2' > mod.py
>>> reload(mod)
<module 'mod' from 'mod.py'>
>>> mod.a
2

Have you looked at pdb?
