扩展类而不访问其__init__方法

class ParentClass:
    def __init__(self, name):
        self.name = name

    def greet(self):
        print("Hello, " + self.name)

class ChildClass(ParentClass):
    def __init__(self, name, age):
        super().__init__(name)  # 调用父类的__init__方法
        self.age = age

    def greet(self):
        super().greet()  # 调用父类的greet方法
        print("You are " + str(self.age) + " years old")

child = ChildClass("Alice", 10)
child.greet()

Hello, Alice
You are 10 years old
