如何使用多執行緒實現一問一答呢？可以使用condition中的notify和wait方法實現，看程式碼

import threading
import time
class XiaoAi(threading.Thread):
    def __init__(self,cond):
        super().__init__(name='小愛')
        self.cond = cond
    def run(self):
        with cond:
            cond.wait()
            print("{}:在".format(self.name))
            cond.notify()
            cond.wait()
            print("{}:好啊".format(self.name))
            cond.notify()
            cond.wait()
            print("{}:君住長江尾".format(self.name))
            cond.notify()
            cond.wait()
            print("{}:共飲長江水".format(self.name))
            cond.notify()
            cond.wait()
            print("{}:此恨何時已".format(self.name))
            cond.notify()
            cond.wait()
            print("{}:定不負相思意".format(self.name))

class Tianmao(threading.Thread):
    def __init__(self,cond):
        super().__init__(name="天貓精靈")
        self.cond =  cond
    def run(self):
        with cond:
            print("{}:小愛同學".format(self.name))
            cond.notify()
            cond.wait()
            print("{}:我們來對詩吧".format(self.name))
            cond.notify()
            cond.wait()
            print("{}:我住長江頭".format(self.name))
            cond.notify()
            cond.wait()
            print("{}:日日思君不見君".format(self.name))
            cond.notify()
            cond.wait()
            print("{}:此水幾時休".format(self.name))
            cond.notify()
            cond.wait()
            print("{}:只願君心似我心".format(self.name))
            cond.notify()


if __name__ == "__main__":
    cond = threading.Condition()
    thread_Ai = XiaoAi(cond)
    thread_Tian = Tianmao(cond)

    thread_Ai.start()
    thread_Tian.start()
