python gevent协程

安装

pip install gevent

import gevent
from gevent import monkey
monkey.patch_all()#捕捉所有阻塞，不止接收gevent.sleep
import time
def f(s):
    print("hello-----%s"%s)
    time.sleep()
def f2(s):
    time.sleep()
    print("hello------%s"%s)
start=time.time()
t=gevent.spawn(f,"f")
t1=gevent.spawn(f2,"f2")
gevent.joinall([t,t1])
end=time.time()
print(end-start)

hello-----f
  hello------f2
