QOTW: "*what* the value is is defined by the operations that the object 
supports (via its type).

*how* the value is represented inside the object is completely 
irrelevant; a Python implementation may use electric charges in small 
capacitors, piles of rocks, diapers,or an endless supply of small guys 
in odd costumes to encode the value inside an object.  Changes to the 
value may be carried out by CPU instructions, caterpillars, toddlers 
with gasmasks, or an endless supply of small guys in odd costumes. The 
only thing that's important is that you can, in your Python program, 
access an objects value via its type, and get other objects back when 
you do." - Fredrik Lundh

"I have never seen a case where a dictionary didn't improve the design." - Ivan
Van Laningham

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

    Python.org's Python Language Website is the traditional
    center of Pythonia
        http://www.python.org
    Notice especially the master FAQ
        http://www.python.org/doc/FAQ.html

    PythonWare complements the digest you're reading with the
    marvelous daily python url
         http://www.pythonware.com/daily  
    Mygale is a news-gathering webcrawler that specializes in (new)
    World-Wide Web articles related to Python.
         http://www.awaretek.com/nowak/mygale.html 
    While cosmetically similar, Mygale and the Daily Python-URL
    are utterly different in their technologies and generally in
    their results.

    For far, FAR more Python reading than any one mind should
    absorb, much of it quite interesting, several pages index
    much of the universe of Pybloggers.

There is *not* an RSS for "Python-URL!"--at least not yet.  Arguments
for and against are occasionally entertained.


Suggestions/corrections for next week's posting are always welcome.
E-mail to <Python-URL at phaseit.net> should get through.

To receive a new issue of this posting in e-mail each Monday morning
(approximately), ask <claird at phaseit.net> to subscribe.  Mention
"Python-URL!".
