协程gevent

协程

gevent里面封装了greenlet，greenlet里面封装了yield

from gevent import monkey
import gevent
import time

# 有耗时操作时需要
monkey.patch_all()

def test(name):
    for i in range(5):
        print(name,i)
        time.sleep(0.5)

gevent.joinall([
    gevent.spawn(test,"work1"),
    gevent.spawn(test,"work2")
])

　　输出

work1 0
work2 0
work1 1
work2 1
work1 2
work2 2
work1 3
work2 3
work1 4
work2 4
