我知道很基础,但是确实不会了www

其中提到的timer模块如下


import threading
import time

def fun_timer():
    global timer, hours
    hours += 1
    if hours > 23:
        hours = 0
    
    timer = threading.Timer(5.0, fun_timer) #5s执行一次fun_timer
    timer.start()


def main():
    global hours

    hours = 0
    fun_timer()  #启动定时器
    while True:
        print()
        command = input("Command:")
        if command == "print":
            print("Now is %-2d"%hours)
        elif command == "quit":
            print("Bye.....")
            timer.cancel()
            break


   

if __name__ =="__main__":
    main()

那你就是解决了没有?
