Python-URL! - Weekly Python News and Links (April 21)

Apr 22, 2003, 05:00 (0 Talkback[s])

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:

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

    David Mertz suggests making repeated string concatenation faster.

    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.
