    The fastest way to consume an iterable until exhaustion:
    When inheriting from a built-in class, it isn't obvious which of

    When importing a module, Python may pick the wrong one due to name
    clashes -- is this avoidable?
    Setting a default encoding for 'print' statements:
    Despite its name, the iglob function (in module glob) isn't completely

    How to parse ill-formed postal addresses:
    The future of Python 3:

    How an extension module (written in C) may perform cleaning tasks:
    "Really, the built-in scope is just a built-in module called builtins,

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

    Readers have recommended the "Planet" site:

    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:

    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.
