进程池线程池

协程

from gevent import monkey;monkey.patch_all()
import gevent,time

def eat(name):
    print('%s eat 1'%name)
    time.sleep(2)
    print('%s eat 2'%name)

def play(name):
    print('%s play 1'%name)
    time.sleep(1)
    print('%s play 2'%name)

g1=gevent.spawn(eat,'egon')
g2=gevent.spawn(play,name='egon')
g1.join()
g2.join()
print('主')

结果是：
egon eat 1
egon play 1
egon play 2
egon eat 2
主
