Python实现分钟倒计时

两分钟倒计时小程序(Python)

import time
minutes = 2
flag = True
while flag:
    for minute in range(minutes, -1, -1):
        if minute == 0:
            flag = False
            break
        for second in range(59, -1, -1):
            time.sleep(1)
            print(f"{minute - 1:02}:{second:02}")

输出：

01:59
01:58
01:57
01:56
01:55
01:54
01:53
01:52
01:51
01:50
01:49

输出太长此处省略，到00:00结束。

输入分钟数的时间倒计时

import sys
import time
times = int(input("请输入倒计时的时间（分钟）："))
times *= 60
leave = 0
while leave < times:
    leave += 1
    min, sec = divmod(times-leave, 60)
    leave_time = str(min)+'分'+str(sec)+'秒'
    sys.stdout.write('r')
    sys.stdout.write('剩余时间：{}'.format(leave_time))
    sys.stdout.flush
    time.sleep(1)
