Note

Doctest Mode

The code-examples in the above tutorials are written in a python-console format. If you wish to easily execute these examples in IPython, use:

%doctest_mode

in the IPython-console. You can then simply copy and paste the examples directly into IPython without having to worry about removing the >>> manually.
