如何接收父类的所有元素？

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

    def print_name(self):
        print("ParentClass name:", self.name)

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

    def print_age(self):
        print("ChildClass age:", self.age)

    def print_name_and_age(self):
        super().print_name()  # 调用父类的普通方法
        self.print_age()  # 调用子类的方法

child = ChildClass("John", 25)
child.print_name_and_age()

ParentClass name: John
ChildClass age: 25
