python 运算符重载,操作符重写

https://blog.csdn.net/JSWANGCHANG/article/details/90739161

需要在类中重新定义几个方法:

    # 重载加法
    def __add__(self, other):
        print("__add__ are called")
        obj = Mynum(self.data + other.data)
        return obj
    #重载减法__sub__
    def __sub__(self,other):
        print("__sub__ are called")
        obj = Mynum(self.data - other.data)
        return obj
    #乘法重载___mul__    _
    def __mul__(self, other):
        print("__mul__ are called")
        obj = Mynum(self.data * other.data)
        return obj
 
    #除法重载___divmod__
    def __truediv__(self, other):
        print("__diymod__ are called")
        obj = Mynum(self.data / other.data)
        return obj
    #地板除: __floordiv__ //
    def __floordiv__(self, other):
        print("__floordiv__ are called")
        obj = Mynum(self.data // other.data)
        return obj
    #取模(求余数)  __mod__  %
    def __mod__(self, other):
        print("__mod__ are called")
        obj = Mynum(self.data % other.data)
        return obj
    #__pow__ 幂运算 **
    def __pow__(self, power, modulo=None):
        print("__pow__ are  called")
        obj = Mynum(self.data ** power.data)
        return obj
