  1. 递归报错”RuntimeError: maximum recursion depth exceeded in cmp”

找到python\Lib\fuctools.py将

convert = {  
    '\_\_lt\_\_': \[('\_\_gt\_\_', lambda self, other: other < self),  
               ('\_\_le\_\_', lambda self, other: not other < self),  
               ('\_\_ge\_\_', lambda self, other: not self < other)\],  
    '\_\_le\_\_': \[('\_\_ge\_\_', lambda self, other: other <= self),  
               ('\_\_lt\_\_', lambda self, other: not other <= self),  
               ('\_\_gt\_\_', lambda self, other: not self <= other)\],  
    '\_\_gt\_\_': \[('\_\_lt\_\_', lambda self, other: other > self),  
               ('\_\_ge\_\_', lambda self, other: not other > self),  
               ('\_\_le\_\_', lambda self, other: not self > other)\],  
    '\_\_ge\_\_': \[('\_\_le\_\_', lambda self, other: other >= self),  
               ('\_\_gt\_\_', lambda self, other: not other >= self),  
               ('\_\_lt\_\_', lambda self, other: not self >= other)\]  
}

替换为

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\_\_': \[('\_\_le\_\_', lambda self, other: (not self >= other) or self == other),  
               ('\_\_gt\_\_', lambda self, other: self >= other and not self == other),  
               ('\_\_lt\_\_', lambda self, other: not self >= other)\]  
}
