Python-URL! - Weekly Python News and Links (December 30)

Jan 05, 2003, 23:00 (0 Talkback[s])

QOTW:  "For my New Year's Resolution, I vow always to close my files
explicitly whenever I can, preferably with a tidy try/finally statement...
:-)"  Peter Hansen

"It rather distresses me that no one appears to have taken the trouble yet
to index all the XML-Python resources in a convenient and unified way." 
Cameron Laird  [but see <URL: http://uche.ogbuji.net/tech/akara/pyxml/ >]

"I was going to say this was going to be a slow week, but you folks
surprised me.  Happy holidays, everybody."  Erik Max Francis


Discussion
    A basic question about SyntaxErrors in what is seemingly trivial
    code leads to the usually helpful troubleshooting mantras
    (indenting, lack of trailing newlines, unterminated string
    literals):

    Tim Peters chimes in at the end of the long "Python vs. Java
    garbage collection" thread (mentioned in last week's Python-URL!
    digest), quoting Guido himself (back in 1992) about the guarantees
    imposed by garbage collection and the calling of __del__ methods,
    hopefully putting the subject to rest once and for all:

    Michele Simionato gives us all a cute "cryptic" Christmas present:
        http://mail.python.org/pipermail/python-list/2002-December/136082.html

    Remember, to use properties, you need to inherit from object, as
    Gonçalo Rodrigues reminds us:
        http://groups.google.com/groups?selm=m9st0v42hqg68i1tni60oujs8rvh90qq6g%404ax.com

    Peter Hansen reminds us the only way to kill a thread is to use
    cooperation with the thread itself:
        http://groups.google.com/groups?selm=3E0F0985.3D4FF3C1%40engcorp.com

    A question about the semantics of the changing division oeprators
    (/ vs. //) leads to extremely precise and clear responses,
    something we all need in the face of changing language semantics:
        http://groups.google.com/groups?threadm=mailman.1041194195.2965.python-list%40python.org

    Mike Meyer shows us how obtaining something often considered
    central to functional programming -- currying -- is so easy to
    achieve in Python:
