有没有办法在Python中覆盖和运算符？

class MyClass:
    def __init__(self, value):
        self.value = value

    def __add__(self, other):
        return MyClass(self.value + other.value)

class MyClass:
    def __init__(self, value):
        self.value = value

    def __add__(self, other):
        return MyClass(self.value + other.value)

    def __sub__(self, other):
        return MyClass(self.value - other.value)
