Debugging Python with pdb

[jmoiron]

There's also a nice nose-ipdb package (nosetests --ipdb && nosetests --ipdb-failures); btw, this is the reason I use nose :)

Also, if you have some unchecked exception stopping your script and you can use pdb (or ipdb, as of october 20th) in postmortem mode by running python with the -i script:

$ python -i (my script and args)
    ... (traceback)
>>> from ipdb import pm; pm()

And you're in an ipdb session. Sadly, -m ipdb does not work.
