No, __call__ function ：

class Person:
    def hello(self,name):
        print("hello"+name)

person=Person()
person.hello(“lisi”)
# Output gets ：hellolisi

Yes __call__ function ：

class Person:
    def __call__(self,name):
        print("hello"+name)

person=Person("lisi")
# Output gets ：hellolisi

That is to say __call__ A function is actually a constructor
