python---生成器_实现迷你聊天机器人

生成器可以使用的方法:
- next(g)
- g.send(”), 给生成器传递值；
- 给yield所在位置发送一个数据, 直到遇到下一个yield停止.

def fun():
    while True:
        print("welcome......")
        receive = yield  "hello"
        print(receive)
# ***fun返回值是一个生成器对象.(因为函数中包含yield关键字)
f = fun()
print(f)
print(next(f))
f.send("微信")

def chat_robot():
    res = ''
    while True:
        receive = yield res
        if 'age' in receive:
            res = "年龄保密"
        elif 'name' in receive:
            res = "siri"
        else:
            res = "i don't know what you say"

def main():
    # 生成器对象
    Robot = chat_robot()
    next(Robot)
    while True:
        send_data = input("粉条>>:")
        if send_data == 'q' or send_data == 'bye':
            print("不聊了， 我也撤了.....")
            break
        print(Robot.send(send_data))

main()
