Countdown Clock: 01:05

Question

How can I create a countdown clock in Python that looks like 00:00 (min & sec) which is on a line of its own. Every time it decreases by one actual second then

Answer 1

Here is the code which counts from 01:05 to 00:00 in MM:SS format.

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)

Answer 2

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)

Answer 3

For the simplicity, this code is able to say you how long it takes until the next desired time, which might be whatever you want to do in your program. In your case, this is a kind of countdown timer.

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))

Then, output is as follows:

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

Good luck with your coding.

Maybe this link will help: Making a Timer in Python 3

And look at my answer, it is same for your too!

Anyway, here is answer:

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!') 

Input:

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

Output # All are on the same line

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!

Answer 5

Apart from formatting your time as minutes and seconds, you'll need to print a carriage return. Set end to \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')

This ensures that the next print overwrites the last line printed:
