如何在Python中连接子类？

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

    def parent_method(self):
        print("This is a method from the parent class")

class ChildClass(ParentClass):
    def __init__(self, parent_param, child_param):
        super().__init__(parent_param)
        self.child_param = child_param

    def child_method(self):
        print("This is a method from the child class")

# 创建子类的实例
child = ChildClass("Parent", "Child")

# 调用子类和父类的方法和属性
child.child_method()
child.parent_method()

# 输出：
# This is a method from the child class
# This is a method from the parent class
