如何在单个if语句中检查两个以上条件

Question

我正在为休息时间设置休息计时器，如果 声明为真

我尝试将其保留在前面的if语句之外 我也尝试使用括号

class Timer(object):

    sec = 0
    minutes = 0
    hours = 0


while True:
    seconds = 5 - sec
    sec = (sec + 1) % 60

    os.system("cls")
    print("You have {hours} hours {minutes} minutes {seconds} seconds until 
        your next smoke break\n".format(hours=hours, minutes=minutes, seconds=seconds))

    time.sleep(1)

    if seconds == 0:
        minutes -= 1
        seconds = 59

        if minutes <= 0:
            hours -= 1
            minutes = 59
            seconds = 59

        if seconds <= 0 and minutes <= 0 and hours <= 0:
            print("Break Time!")
            hours = 0
            seconds = 0
            minutes = 0
            break

我希望输出结果为true，但实际输出为false
