定义"method_called"..如何在每次调用类的任何函数时调用一个钩子方法？

def hook_decorator(func):
    def wrapper(instance, *args, **kwargs):
        instance.method_called()
        return func(instance, *args, **kwargs)
    return wrapper

class MyClass:
    def method_called(self):
        print("Hook method called!")

    @hook_decorator
    def method1(self):
        print("Method 1 called!")

    @hook_decorator
    def method2(self):
        print("Method 2 called!")

# 使用示例
my_instance = MyClass()
my_instance.method1()  # 输出：Hook method called! Method 1 called!
my_instance.method2()  # 输出：Hook method called! Method 2 called!
