Debugging in Python

Test driven development, clean code, and the occasional printf statement can go a long way towards debugging programs. But I remain a bit surprised by the number of developers who seem to take offense when users ask about a debugger for python. For those who do find reason for using a debugger I recommend:

• Debugging in Python
• The Python Debugger (Library Reference)

The former is a friendlier read with a tutorial flavor, while the latter provides a definitive reference.
