This is great, thanks Jure. For whatever reason I find it difficult to read documentation, I work much better with code examples, they speak to me much more clearly than a text explanation.
I think the online documentation for Python stdlib is quite good. What I don't understand is why more of it is not available in help() from Python itself. For all the docstring features in Python, the stdlib somehow just has second rate documentation in module and function docstrings!
Compare with numpy and scipy, where the docstrings are comprehensive (there's a correspondance between online and embedded docs.)
