I find myself frequently using Python's interpreter to work with databases, files, etc -- basically a lot of manual formatting of semi-structured data. I don't properly save and clean up the useful bits as often as I would like. Is there a way to save my input into the shell (db connections, variable assignments, little for loops and bits of logic) -- some history of the interactive session? If I use something like
script I get too much stdout noise. I don't really need to pickle all the objects -- though if there is a solution that does that, it would be OK. Ideally I would just be left with a script that ran as the one I created interactively, and I could just delete the bits I didn't need. Is there a package that does this, or a DIY approach?
UPDATE: I am really amazed at the quality and usefulness of these packages. For those with a similar itch:
I am converted, these really fill a need between interpreter and editor.
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.
