初识python： 生成器并行（做包子，吃包子)

知识点：

send(i) ：唤醒yield，并将 i 的值传给 yield

#!/user/bin env python
# author:Simple-Sir
# time:20181020
# 单线程并发：做一个包子，两个人吃
import time
# 吃包子生成器
def chibaozi(name):
    print('%s想吃包子了！' %name)
    while True:
        baozi = yield
        print('第%s个包子来了，被%s吃了一半！'%(baozi,name))

# 逻辑解析
# c = chibaozi('SimpleGirl')
# c.__next__()  # 唤醒yield
# b1='牛肉包子'
# c.send(b1)  # 注：唤醒yield，并将b1的值传给 yield

# 做包子生成器
def zuobaozi(name):
    c1 = chibaozi('SimpleSir')
    c2 = chibaozi('SimpleGirl')
    c1.__next__()
    c2.__next__()
    print('%s开始做包子了！'%name)
    for i in range(1,6):
        time.sleep(1)
        print('%s做了1个包子！'%name)
        c1.send(i)
        c2.send(i)

# 调用函数
zuobaozi('SimpleSir')

 

执行结果：
