协程的简单实现

import time
# yield配合next使用
def work1():
    while True:
        print("----work1---")
        yield
        time.sleep(0.3)

def work2():
    while True:
        print("----work2---")
        yield
        time.sleep(0.3)

def main():
    w1 = work1()
    w2 = work2()
    while True:
        next(w1)
        next(w2)

if __name__ == "__main__":
    main( )
