python的協程（可實現高並發）

一、生成器例子

def f():
    print('你好')
 name = yield 44
 print(name)
 yield 55
g = f()
next(g)
print(g.send('zhou'))

二、

from builtins import print, next, range


def consumer(name):
 print('---->開始吃包子了......')
 while True:
 baozi = yield
 print('%s 吃了包子編號為：%s'%(name,baozi))
def producer():
 next(conn)
 next(conn2)
 for i in range(5):
 conn.send(i)
 conn2.send(i)

if __name__ == '__main__':
 conn = consumer('張三')
 conn2 = consumer('李四')
 p = producer()
