Python -如何从不同的方法触发方法中的操作

class MyClass:
    def my_method(self):
        print("操作被触发了")

obj = MyClass()
obj.my_method()  # 直接调用方法

class Event:
    def __init__(self):
        self._handlers = []

    def add_handler(self, handler):
        self._handlers.append(handler)

    def trigger(self):
        for handler in self._handlers:
            handler()

class MyClass:
    def __init__(self):
        self.event = Event()
        self.event.add_handler(self.my_method)

    def my_method(self):
        print("操作被触发了")

obj = MyClass()
obj.event.trigger()  # 触发事件，间接调用方法

def callback():
    print("操作被触发了")

def perform_operation(callback):
    # 模拟一些操作
    print("执行操作...")
    callback()  # 调用回调函数

perform_operation(callback)  # 传递回调函数并触发

def trigger_operation(func):
    def wrapper(*args, **kwargs):
        print("准备触发操作...")
        result = func(*args, **kwargs)
        print("操作已触发")
        return result
    return wrapper

class MyClass:
    @trigger_operation
    def my_method(self):
        print("操作被触发了")

obj = MyClass()
obj.my_method()  # 使用装饰器触发方法

import threading

class MyClass:
    def my_method(self):
        print("操作被触发了")

def trigger_in_thread(obj):
    obj.my_method()

obj = MyClass()
thread = threading.Thread(target=trigger_in_thread, args=(obj,))
thread.start()  # 在新线程中触发方法
thread.join()
