staticmethod自己定制

class StaticMethod:
    def __init__(self,func):
        self.func=func

    def __get__(self, instance, owner): #类来调用,instance为None,owner为类本身,实例来调用,instance为实例,owner为类本身,
        print("hhahaha")
        def feedback(*args,**kwargs):
            print('在这里可以加功能啊...')
            return self.func(*args,**kwargs)
        return feedback

class People:
    @StaticMethod# say_hi=StaticMethod(say_hi)
    def say_hi(x,y,z):
        print('------>',x,y,z)

People.say_hi(1,2,3)
#
# p1=People()
# p1.say_hi(4,5,6)
