QOTW: "Python is more concerned with making it easy to write good programs
than difficult to write bad ones." - Steve Holden

"Scientists build so that they can learn. Programmers and engineers learn
so that they can build." - Magnus Lycka

"It happens that old Java programmers make one module per class when they
start using Python. That's more or less equivalent of never using more
than 8.3 characters in filenames in modern operating systems, or to make
a detour on your way to work because there used to be a fence blocking the
shortest way a long time ago." - Magnus Lycka


    Python doesn't currently have a case or switch statement. Case blocks
    are easily simulated with if, elif, and else, but would Python's
    readability benefit from having it built in?:

    A Podcast worth listening to at last. Guido speaks on Python's history
    and community:

    If your class implements __eq__ but not __ne__, (a = b) does not imply
    !(a != b). If this something that should be fixed, or just a "gotcha"?
        http://groups-beta.google.com/group/comp.lang.python/brow...
    
    John Machin instructively analyzes several of Excel's defects as a
    data-management vehicle, obliquely highlighting Python's Zen.  Tim
    Roberts follows up with a small but potentially crucial addendum
    pertinent, among others, to those who deal with USA "zip codes":

    Recent (unreleased) work on distutils allows you to automatically
    upload packages to PyPI:

    Text files and line endings; Python helps you out on Windows, which can
    be a little confusing:

    Kalle wants to protect his instance attributes. He's warned off the
    idea, but at the same time, alex23 demonstrates an interesting way of
    doing it using properties():

    Creating a Python iterator by wrapping any callable:

    Richard Lewis wants resumable exceptions. Python doesn't have them,
    but Peter Hansen shows him how to achieve what he wants, and Willem
    shows us how resumable exceptions work in Lisp:
        http://groups-beta.google.com/group/comp.lang.python/brow...
    
    Jan Danielsson is confused about the difference between __str__ and
    __repr__, and what they are both for:

    The Kamaelia Framework; communicating with and linking Python generators:
        http://www.bbc.co.uk/rd/pubs/whp/whp113.shtml
        
    Ron Adams proposes an "also" block to be executed if a "for" loop's
    "else" block isn't, and more controversially, that the "else" block's
    meaning be switched:
        http://groups-beta.google.com/group/comp.lang.python/brow...
        
    How you convince your marketing drones that switching from Python to
    Java would be A Bad Thing?
        http://groups-beta.google.com/group/comp.lang.python/brow...
        
    Why should an ambitious 14-year-old look at Python? (And why source-code
    hiding is a waste of time.)
