How one can create a Countdown Timer in Python

If you should depend down a selected period of time, say for instance, when a token is about to run out, then a countdown timer can be helpful.

Step 1 – Writing the Python code

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

Possibility 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))

Possibility 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.

Notice: If you happen to use MacOS, it will 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

If you happen to use bash then do that:

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

If you happen to 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 possibly can simply name depend and the applying will begin.

What enter does it anticipate?

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

If you happen to enter 30, then it can depend down for 30 seconds.

If you happen to enter 3600 (60seconds x 60minutes), then it can depend down for an hour.

and many others.
