I also have the perl books and like cookbook. I'm in the process of
converting a suite of perl modules to python. Partly to learn python,
but mainly to get more maintainability at the package grows in
complexity. Auto-conversion looked pretty hopeless, so I just open
two buffers in emacs. Read the perl in one and type python in the
other. Key insights:
1. Get python-mode.el installed. It makes python formatting trivial.
2. Work out the regular expression tricks early -- I'm currently
looking for a python idiom for
s/@@([a-z]+)@@/$lookup{$1}/g
Python needs a Cookbook. Except for copyright issues, I'd say just
redo all the Perl Cookbook examples in python -- or maybe O'Rielly has
one in the works already.
