    SOLUTION: 修改h:\64soft\python27\Lib\functools.py里的convert,如下

    convert = {
            '__lt__': [('__gt__', lambda self, other: not (self < other or self == other)),
                       ('__le__', lambda self, other: self < other or self == other),
                       ('__ge__', lambda self, other: not self < other)],
            '__le__': [('__ge__', lambda self, other: not self <= other or self == other),
                       ('__lt__', lambda self, other: self <= other and not self == other),
                       ('__gt__', lambda self, other: not self <= other)],
            '__gt__': [('__lt__', lambda self, other: not (self > other or self == other)),
                       ('__ge__', lambda self, other: self > other or self == other),
                       ('__le__', lambda self, other: not self > other)],
            '__ge__ ': [('__le__', lambda self, other: (not self >= other) or self == other),
                       ('__gt__', lambda self, other: self >= other and not self == other),
                       ('__lt__', lambda self, other: not self >= other)]
        }
