Question

python中super的使用

class Human(object):
def __init__(self, name):
self.__name = name
class Man(Human):
def __init__(self, name, has_wife):
super(Man, self).__init__(name)
self.__has_wife = has_wife
继承的时候 super(Man, self).__init__(name) 中init后面的括号要把父类中所有的参数都写进去吗？
小白自学求解

Answer 1

Yes, and since py3.5,  `super(Man, self).__init__(name, has_wife)` can be replaced as below:

super().__init__(name, has_wife)

追问

可是父类中没有has wife这个参数啊？？？

追答

super().__init__(name)

追问

意思就是父类中的init有多少个参数，super后面根的init就有多少参数是吗？谢谢！

追答

That's right. Or if you don't know how many args does the super class method have, use this:

super().__init__(*args, **kwargs)

追问

谢谢！！！
