【脚本语言系列】关于Python基础知识协程，你需要知道的事

如何使用协程(Coroutine)

• 协程

# -*- coding:utf-8 -*-
def fib();
    a,b = 0,1
    while Ture:
        yield a
        a,b = b,a+b
for i in fib():
    print i 

# -*- coding:utf-8 -*-
def grep(pattern):
    print "Searching for", pattern
    while True:
        line = (yield)
        if pattern in line:
            print line

search = grep("coroutine")
next(search)
# Searching for coroutine
search.send("Here you are.")
search.send("This is coroutine.")
search.send("I get you.")
search.close()

Searching for coroutine
This is coroutine.

• 生成器

# -*- coding:utf-8 -*-
def fib():
    a,b = 0,1
    while True:
        yield a
        a,b = b, a+b
for i in fib():
    print i

什么是协程(Coroutine)

协程用来消费数据；对应地，生成器用来产生数据；
