I would like to point out that it isn't entirely obvious where to find documentation for this particular thing. I know from experience where to go, but I remember spending a long time trying to hunt this down.
For reference, you may want to check out the index of the language reference manual. http://www.python.org/doc/2.4.2/ref/genindex.html -- http://mail.python.org/mailman/listinfo/python-list
