协程gevent

import gevent
from gevent import monkey

# monkey.patch_all()   # 补丁包，协程有IO等待时，触发协程切换

def work1():
    for i in range(10):
        print(f'--------work1------{i}')
        # time.sleep(0.1)
        gevent.sleep(0.1)


def work2():
    for i in range(10):
        print(f'--------work2------{i}')
        # time.sleep(0.1)
        gevent.sleep(0.1)  # 触发协程切换


g1 = gevent.spawn(work1)  # gevent.spawn() 执行任务，首次创建协程后，会直接执行任务
g2 = gevent.spawn(work2)
g1.join()  # 让主线程等待协程执行完成
g2.join()
