create a Countdown Timer in Python

If it’s good to depend down a particular period of time, say for instance, when a token is ready to run out, then a countdown timer shall be helpful.

Step 1 – Writing the Python code

Place the next Python code in a file known as countdowntimer.py

Choice 1 – Textual content output

import time

def countdown(t):
  whereas t:
    minutes, secs = divmod(t, 60)
    timer = '{:02d}:{:02d}'.format(minutes, secs)
    print(timer, finish="r")
    time.sleep(1)
    t -= 1

  print('Countdown time has elapsed!!')

t = enter("Enter the time in seconds: ")

countdown(int(t))

Choice 2 – Textual content and speech output

Right here we additionally invoke say which speaks out the textual content. That is solely native to some working programs.

Observe: In the event you use MacOS, this can work out the field for you!

import time
import os

def countdown(t):
  whereas t:
    minutes, secs = divmod(t, 60)
    timer = '{:02d}:{:02d}'.format(minutes, secs)
    print(timer, finish="r")
    time.sleep(1)
    t -= 1

  txt = 'Countdown time has elapsed!!'
  print(txt)
  os.system('say "'+txt+'"')

t = enter("Enter the time in seconds: ")

countdown(int(t))

Step 2 – Calling the Python code

python3 <path_to_file>/countdowntimer.py

Elective Step 3 – Create an Alias

In the event you use bash then do that:

echo "alias depend='python3 <path_to_file>/countdowntimer.py'" >> ~/.bash_profile

In the event you use zsh then do that:

echo "alias depend='python3 <path_to_file>/countdowntimer.py'" >> ~/.zshrc

Now when you’ve reloaded the terminal session by doing one of many following:

1. supply ~/.bash_profile
2. supply ~/.zshrc
3. Shut and reopen your terminal

You’ll be able to simply name depend and the applying will begin.

What enter does it count on?

If you first run the applying, you possibly can specify the quantity of seconds to depend down from.

In the event you enter 30, then it should depend down for 30 seconds.

In the event you enter 3600 (60seconds x 60minutes), then it should depend down for an hour.

and so on.
