| See: http://www.python.org/doc/2.3.5/ref/sequence-types.html, which says, for example, that __getitem__(self, key) should raise an IndexError if key is not in the container. However, built-in dicts raise KeyError instead, and http:// www.python.org/doc/2.3.5/lib/module-exceptions.html#l2h-289 implies that this is the correct behavior. This appears to be incorrect in the current documentation as well as in the 2.3.5 docs. | ||
