How to save a Python interactive session?

by

IPython is extremely useful if you like using interactive sessions. For example for your use-case there is the %save magic command, you just input %save my_useful_session 10-20 23 to save input lines 10 to 20 and 23 to my_useful_session.py (to help with this, every line is prefixed by its number).

Furthermore, the documentation states:

This function uses the same syntax as %history for input ranges, then saves the lines to the filename you specify.

This allows for example, to reference older sessions, such as

%save current_session ~0/
%save previous_session ~1/

Look at the videos on the presentation page to get a quick overview of the features.
