是否可以在运行时替换函数/方法装饰器？[python]

import functools

def my_decorator(func):
    @functools.wraps(func)
    def wrapper(*args, **kwargs):
        # 在这里添加您的替换装饰器逻辑
        return func(*args, **kwargs)
    return wrapper

def my_function():
    print("Hello, world!")

my_function = my_decorator(my_function)

class MyDecorator:
    def __init__(self, func):
        self.func = func

    def __call__(self, *args, **kwargs):
        # 在这里添加您的替换装饰器逻辑
        return self.func(*args, **kwargs)

def my_function():
    print("Hello, world!")

my_function = MyDecorator(my_function)
