python 递归调用默认上限:1000次
1、比较运算符:
__cmp__(self,other)比较
__eq__(self,other)相等
__lt__(self,other)小于
__gt__(self,other)大于
2、逻辑运算符:
__or__(self,other)
__and__(self,other)
3、数学运算符:
__add__(self,other) +
__sub__(self,other) -
__mul__(self,other) *
__div__(self,other) /
4、转换为字符串:
__str__
__repr__
__unicode__
5、展现对象属性:
__dir__
6、设置对象属性:
__setattr__(self,name,value)
7、查询对象属性:
__getattr__(self,name)
__getattribute__(self,name)
8、删除对象属性:
__delattr__(self,name)
