Python IDE that you can highlight a method/class and jump to its definition -

I am trying to use textmate, but I find it hard to navigate a project.

I agree that I do not know IDE well enough.

Is it possible to expose the class or method and jump for its definition?

I'm not sure that I understand the question, but if you search the IDE for Python So I strongly recommend and have a look at you

This is the most feature-rich IDE for Python so far and it has a really active development team. And have I told it its free and open source?
