那么,在python中如何实现回调函数呢,看代码: # 被调用的回调函数 def my_callback(input): print("function my_callback was called with %s input" % (input,)) # 调用函数 def caller(input, func): func(input) for i in range(5): caller(i, my_callback) 回调函数场景应用场景 回调函数常用于以...
但是有些库函数(library function)却要求应用先传给它一个函数,好在合适的时候调用,以完成目标任务。这个被传入的、后又被调用的函数就称为回调函数(callback function)。 打个比方,有一家旅馆提供叫醒服务,但是要求旅客自己决定叫醒的方法。可以是打客房电话,也可以是派服务员去敲门,睡得死怕耽误事的,还可以要求...

例如：def my_callback(input): print "function my_callback was called with %s input" % (input,)def caller(input, func): func(input)for i in range(5): caller(i, my_callback)执行结果是：function my_callback was called with 0 inputfunction my_callback was called...
