I recommend pdb; there's a How-To klm wrote on the zope.org site called
'Debugging Zope Python Code', that recommends inserting something like

import pdb
pdb.set_trace()

at the part of the code that you want to have it drop down into the
debugger at, and then you can step through and find out the value of
various expressions as you're running things, call functions, etc.

Mr. Creosote is also my favorite - check out the MrCreosote subdirectory
of pcgi/ in your Zope installation; the nice thing about Mr. Creosote is
you can have it send debugging info to another machine (UDP packets)
