For a guy like me who uses JOE:

joe somefile.py
<code> <code> <code>
^K S ^K Z
python somefile.py
<crash>
fg
<debug>
^K S ^K Z
^P ^P <Enter>
<crash>
fg
<debug>
(ad infinitum)

screen makes a sweet job of this, too, and lets pydoc enter the equation.

<debug> mostly consists of tossing print statments in wherever there might
be something wrong.  Rather than unit testing, I prefer to test,
immediately and thoroughly, any changes I make.  Failure to do so almost
always results in hard-to-find errors (for me, at least).  A few asserts
here and there don't hurt, either (though I mostly use them to verify
weird logic).
