import greenlet
# 绿色线程 (实现协程的一种方式)

import time

def task1():
    print("task1 run")
    g2.switch()
    print("task1 over")
    g2.switch()

def task2():
    print("task2 run")
    g1.switch()
    time.sleep(1)
    print("task2 over")



g1 = greenlet.greenlet(task1)
g2 = greenlet.greenlet(task2)
g1.switch()

print("主over")
# task1 run
# task2 run
# task1 over
# task2 over
