python回调函数的使用方法

有两种类型的回调函数:

代码如下:

blocking callbacks (also known as synchronous callbacks or just callbacks)deferred callbacks (also known as asynchronous callbacks)

代码如下:

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)
