There is no direct Python equivalent to Perlmonks.

Google Is Your Friend.

The best location for general Python-related questions is either python-list, aka USENET's comp.lang.python (for basic-advanced questions), the python-tutor mailing list for novice questions, or reddit's learnpython. (With few exceptions that also involve Perl) Perlmonks is not the place for Python questions.

No, Really. Google Is Your Friend.

(Personally) the best book for someone coming from another language is the Python Cookbook. It's totally different from the Perl Cookbook, though.

The very moribund PLEAC translates much of the Perl Cookbook v1's code into various languages, including Python.
