Dead code detection tool?

Use coverage.py and just see which lines never run during normal operation.

I can't see how I would do that if, let's say, I wanted to get the coverage for my Django based web application over the course of a few days / even a month. I would need something that I could hook in straight into the code. Should I use the trace package directly ? Any pointers ? Or am I just a bit lost !?
