Python Information
Your primary source of information is the main Python website
www.python.org. It contains pointers
to the system itself, all the documentation you would ever want, as
well as a Python mode for Emacs.
Some pages that you should
bookmark include the
Python tutorial,
Python Library Reference,
and within that document the list of
built-in functions.
They also have compiled a list of
books about Python.;
I've only seen the Ascher and Lutz's "Learning Python" and Beazley's
"Python Essential Refernce".
The former is a gentle introduction that probably isn't worth the
money unless you're very unsure of your programming ability and the
on-line docs don't grab you. I've found the Beazley book to be
useful.
On the off chance that there are any Lisp hackers in the
class, Peter Norvig has put together a nice
comparison of Lisp and Python.
