Dr. Dobb's Python-URL! - weekly Python news and links (Apr 21)

[Steven Taschuk]

QOTW:  "This suggests that "nobody" doesn't eval to 0, but at least 3."
                                            -- Christian Tismer

"This is one thing Grothendieck got absolutely right: one should
always, always, always consider the relative situation (i.e. think
about morphisms rather than maps)." --  Michael Hudson


Discussion:
    Much ado about the appropriate uses of __str__ and __repr__ (with
    a digression on orbital mechanics, for flavour).
        <http://groups.google.com/groups?th=24b817d49ec3a59b>

    Roy Smith illustrates the "Big O" notation by an informal analysis
    of everyone's favourite Python performance gotcha -- repeated
    string concatenation.
        <http://groups.google.com/groups?th=274dcb113af97b01#link3>

    David Mertz suggests making repeated string concatenation faster.
        <http://groups.google.com/groups?th=5968aec796657f37>

    Continued from last week: the state of the Python web programming
    world; further development of the theme "gee, there's a lot of
    frameworks"; ruminations on simplifying the situation.
        <http://groups.google.com/groups?th=903e379430bffdfd>

    are utterly different in their technologies and generally in
    their results.
