python 實現(xiàn)類重載（類似C#的類重載，但是遠不如C#的類重載好用）

pip install multipledispatch -i https://mirrors.aliyun.com/pypi/simple

from multipledispatch import dispatch

class MyClass:
    ab = 11234
    def __init__(self):
        self.aa = 1
    @dispatch()
    def calculate(self):
        self.aa = 1111

    @dispatch(int)
    def calculate(self, a):
        self._calculate(a)

    @classmethod
    def _calculate(cls, ip):
        print(cls.ab)
        print(ip)

obj = MyClass()
obj.calculate()
obj.calculate(5)
print(obj.aa)
