[IPython-User] Reusable notebooks
Mon Jul 23 15:00:34 CDT 2012
This is a topic that's of interest to many of us working on IPython -
how can we combine our quick, exploratory style of coding with
something lasting that can be verified and replicated. We don't claim
to have all the answers, but we think the notebook is a very useful
step in that direction.

I would suggest two possible approaches:
- Staying in Python, refactor your data analysis so that calling a
single function runs all the steps. Then running it for several
datafiles is as simple as writing a for loop at the bottom of the
- Save the notebook as a Python script (either via the 'File >
Download as' menu, or start the notebook server with the --script
option to get a .py file whenever you save a notebook). Then you can
open it in an editor and adjust it from interactive-use code to
something that you can run from the command line.
I've used both of these approaches myself - what makes sense will
depend on the kind of analysis you're doing, and what sort of workflow
you want to fit it into - e.g. I have a Makefile to control parts of
my data analysis, which lends itself to a script & file based
