    A long thread about multiprocessing, multithreading, the GIL, and how
    Python behaves in a multicore/multiple CPU environment:
    Using __del__ and atexit to execute code when interpreter shuts down:
    Several ways to keep a bunch of named constants: into a dictionary, as

    Handling keyboard input immediately (without waiting for <enter> key):
    After discovering some corner cases in the set implementation, this

    Using the right algorithm and data structure, the time to compare two

    Replacing a method with an arbitrary callable object:

Everything Python-related you want is probably one or two clicks away in

    Just beginning with Python?  This page is a great place to start:

    The Python Papers aims to publish "the efforts of Python enthusiats":
    The Python Magazine is a technical monthly devoted to Python:

    Readers have recommended the "Planet" sites:

    comp.lang.python.announce announces new Python software.  Be
    sure to scan this newsgroup weekly.

    Python411 indexes "podcasts ... to help people learn Python ..."
    Updates appear more-than-weekly:

    The Python Package Index catalogues packages.

    The somewhat older Vaults of Parnassus ambitiously collects references
    to all sorts of Python resources.

    Much of Python's real work takes place on Special-Interest Group
    mailing lists

    Python Success Stories--from air-traffic control to on-line
    match-making--can inspire you or decision-makers to whom you're
    subject with a vision of what the language makes practical.

    The Python Software Foundation (PSF) has replaced the Python
    Consortium as an independent nexus of activity.  It has official
    responsibility for Python's development and maintenance.
    Among the ways you can support PSF is with a donation.

    The Summary of Python Tracker Issues is an automatically generated
    report summarizing new bugs, closed ones, and patch submissions.

    Although unmaintained since 2002, the Cetus collection of Python
    hyperlinks retains a few gems.
