如何从子实例调用父函数？

class Parent:
    def parent_method(self):
        print("Parent method called")

class Child(Parent):
    def parent_method(self):
        super().parent_method()
        print("Child method called")

child = Child()
child.parent_method()

class Parent:
    def parent_method(self):
        print("Parent method called")

class Child(Parent):
    @staticmethod
    def parent_method():
        Parent.parent_method()

child = Child()
child.parent_method()

class Parent:
    def parent_method(self):
        print("Parent method called")

class Child(Parent):
    def child_method(self):
        self.parent_method()

child = Child()
child.child_method()
