倒计时时钟:01:05

标签: python python-3.4

如何在Python中创建倒计时时钟,看起来像00:00(min& sec),它自己就行了。每当它减少一个实际秒时,旧计时器应该在其线路上用一个低一秒的新计时器替换: 01:00变为00:59,实际上会点击00:00

这是我开始使用但想要转换的基本计时器:

def countdown(t):
    import time
    print('This window will remain open for 3 more seconds...')
    while t >= 0:
        print(t, end='...')
        time.sleep(1)
        t -= 1
    print('Goodbye! \n \n \n \n \n')

t=3

我还想确保Goodbye!之后(很可能在函数之外)的任何内容都在它自己的行上。

结果: 3...2...1...0...Goodbye!

我知道这与其他倒计时问题相似,但我相信它有自己的转折。

除了将时间格式化为分钟和秒钟之外,您还需要打印回车。将end设为\r

import time

def countdown(t):
    while t:
        mins, secs = divmod(t, 60)
        timeformat = '{:02d}:{:02d}'.format(mins, secs)
        print(timeformat, end='\r')
        time.sleep(1)
        t -= 1
    print('Goodbye!\n\n\n\n\n')

这可确保 next 打印覆盖打印的最后一行:

countdown

以下是从MM:SS格式的01:05到00:00计算的代码。

Python 3:

import time
def countdown(p,q):
    i=p
    j=q
    k=0
    while True:
        if(j==-1):
            j=59
            i -=1
        if(j > 9):  
            print(str(k)+str(i)+":"+str(j), end="\r")
        else:
            print(str(k)+str(i)+":"+str(k)+str(j), end="\r")
        time.sleep(1)
        j -= 1
        if(i==0 and j==-1):
            break
    if(i==0 and j==-1):
        print("Goodbye!", end="\r")
        time.sleep(1)
countdown(1,5) #countdown(min,sec)

Python 2:

import time
def countdown(p,q):
    i=p
    j=q
    k=0
    while True:
        if(j==-1):
            j=59
            i -=1
        if(j > 9):  
            print "\r"+str(k)+str(i)+":"+str(j),
        else:
            print "\r"+str(k)+str(i)+":"+str(k)+str(j),
        time.sleep(1)
        j -= 1
        if(i==0 and j==-1):
            break
    if(i==0 and j==-1):
        print "\rGoodbye!"
        time.sleep(1)
countdown(1,5) #countdown(min,sec)

为简单起见,此代码可以告诉您在下一个所需时间之前需要多长时间,这可能是您想要在程序中执行的任何操作。在你的情况下,这是一种倒数计时器。

from datetime import datetime

x=datetime.today()
y=x.replace(day=x.day+1, hour=3, minute=1, second=0, microsecond=0)
delta_t=y-x
secs=delta_t.seconds+1

second = (secs % 60)
minut = (secs / 60) % 60
hour = (secs / 3600)
print ("Seconds: %s " % (second))
print ("Minute: %s " % (minut))
print ("Hour: %s" % (hour))

print ("Time is %s:%s:%s" % (hour, minut, second))

然后,输出如下:

Seconds: 50 
Minute: 32 
Hour: 12
Time is 12:32:50

祝你的编码好运。

import time
import sys

print(' ')
print('Countdown Timer, By Adam Gay')
print(' ')
print('Instructions: Input time to countdown from.')
print(' ')

c=':'

hourz=input('Hours: ')
minz=input('Minutes: ')
secz=input('Seconds: ')
print(' ')

hour=int(hourz)
min=int(minz)
sec=int(secz)

while hour > -1:
    while min > -1:
        while sec > 0:
            sec=sec-1
            time.sleep(1)
            sec1 = ('%02.f' % sec)  # format
            min1 = ('%02.f' % min)
            hour1 = ('%02.f' % hour)
            sys.stdout.write('\r' + str(hour1) + c + str(min1) + c + str(sec1))

        min=min-1
        sec=60
    hour=hour-1
    min=59

Print('Countdown Complete.')
time.sleep(30)

看看我的回答,对你也一样!

无论如何,这是答案:

import time
import os
hour = int(input('Enter any amount of hours you want -+==> '))
minute = int(input('Enter any amount of minutes you want -+==> '))
second = int(input('Enter any amount of seconds you want -+==> '))
time = hour*10800 + minute*3600 + second*60
print('{}:{}:{}'.format(hour,minute,second))
while time > 0:
   time = time - 1
   seconds = (time // 60) % 60
   minutes = (time // 3600)
   hours = (time // 10800)
   print('Time Left -+==> ',hours,':',minutes,':',seconds,)
   os.system("CLS")
if time == 0:
   print('Time Is Over!') 

输入:

Enter any amount of hours you want -+==> 0
Enter any amount of minutes you want -+==> 0 
Enter any amount of seconds you want -+==> 10

输出#全部在同一行

Time Left -+==> 0:0:10
Time Left -+==> 0:0:9
Time Left -+==> 0:0:8
Time Left -+==> 0:0:7
Time Left -+==> 0:0:6
Time Left -+==> 0:0:5
Time Left -+==> 0:0:4
Time Left -+==> 0:0:3
Time Left -+==> 0:0:2
Time Left -+==> 0:0:1
Time Left -+==> 0:0:0
Time Is Over!
