如何从子类（在 Python 中）更改父类的变量？ [复制]

Question

在 python 中实践继承

我在 python 上练习继承。我不确定如何更改父类的变量名。

# Parent Class
class Family_Member():
    def __init__(self, name):
        self.name = name
    def catch_phrase(self):
        print("I am a family member")
# Child Class
class Mum(Family_Member):
    def __init__(self):
        Family_Member.__init__(self)
# Attempting to change variable of parent class from child class
My_Mum = Mum("Kerry")

这给了我

TypeError: __init__() takes 1 positional argument but 2 were given

问题

1. 为什么会发生这种情况？如何命名我的成员 Kerry 而不会出现此错误

2. 为什么我在子类中不包含init函数时不会出现这个错误。例如，此代码有效

   # Attempt 2
   class Family_Member():
        def __init__(self, name):
            self.name = name
        def catch_phrase(self):
            print("I am a family member")
    class Mum(Family_Member): # THIS CLASS IS NOW EMPTY
       pass
     My_Mum = Mum("Kerry")
        print(My_Mum.name)
   

Answer 1

class Family_Member():
    def __init__(self, name):
        self.name = name
    def catch_phrase(self):
        print("I am a family member")
        
class Mum(Family_Member):
    def __init__(self, name):
        Family_Member.__init__(self, name)
        
My_Mum = Mum("Kerry")

应该可以吧？
