Debugging options w/ Python, Flask and Sublime Text 2

Question

I have just switched to Sublime Text 2 for my Python development. I usually do web programming with the Flask micro framework.

What are my debugging options with this combination, and how do I set it up? I'm working on Windows 7.

Use pdb:

import pdb; pdb.set_trace()

(or the even better pdb++)

Also, Flask already include Werkzeug which contains an interactive JavaScript based in-browser debugger, I highly recommend you utilize it.

(if your Flask uses uWSGI you can check out this guide to make Werkzeug debugger work: debugging flask application under uWSGI)

Thx for your answer, but will it be possible to set breakpoints in code and step through it if I use pdb?

@happygoat yes, you can simply put import pdb; pdb.set_trace() to the line you want to break at.

Real men and women use ipdb pypi.python.org/pypi/ipdb (and spend a less time to do it, because arrow keys and history works)

@MikkoOhtamaa thanks for the suggestions, I haven't used it before but will give it a try :)

Also worth noting; Once you've hit the break point and munged/inspected whatever you want to, you can continue the execution with continue - maybe continue() if you not using ipdb.
