How to Create a Countdown Timer in Python

[Saltyu]

In this tutorial, we will program 'How to Create a Countdown Timer in Python'. We will learn how to create a proper countdown timer. The main goal here is to create a reliable countdown timer that can be used to time any events. I will provide a sample program to demonstrate the actual coding of this tutorial.

This topic is very easy to understand; just follow the instructions I provide, and you can also do it yourself with ease. The program I will show you covers the basics of programming for creating a countdown timer. I will do my best to provide you with the easiest method of creating this countdown timer program. So, let's start with the coding.

Getting Started:

First you will have to download & install the Python IDLE's, here's the link for the Integrated Development And Learning Environment for Python https://www.python.org/downloads/.

Creating Main Function

This is the main function of the application. The following code will display a simple GUI in terminal console that will display the countdown timer. To do this, simply copy and paste these blocks of code into the IDLE text editor.

1. import
   
   time
   
2. 
   
3. def
   
   countdown(
   
   time_sec)
   
   :
   
4. while
   
   time_sec:
   
5. mins,
   
   secs =
   
   divmod
   
   (
   
   time_sec,
   
   60
   
   )
   
6. timeformat =
   
   '{:02d}:{:02d}'
   
   .format
   
   (
   
   mins,
   
   secs)
   
7. print
   
   (
   
   timeformat,
   
   end=
   
   '\r
   
   '
   
   )
   
8. print
   
   (
   
   "\n
   
   "
   
   )
   
9. time
   
   .sleep
   
   (
   
   1
   
   )
   
10. time_sec -=
    
    1
    
11. 
    
12. print
    
    (
    
    "Timer end"
    
    )
    
13. 
    
14. 
    
15. while
    
    True
    
    :
    
16. ret=
    
    False
    
17. 
    
18. print
    
    (
    
    "\n
    
    \n
    
    =============== Countdown Timer ===============\n
    
    \n
    
    "
    
    )
    
19. 
    
20. 
    
21. sec=
    
    int
    
    (
    
    input
    
    (
    
    "Set your timer in sec: "
    
    )
    
    )
    
22. 
    
23. countdown(
    
    sec)
    
24. 
    
25. 
    
26. user_input=
    
    input
    
    (
    
    "\n
    
    \n
    
    Try Again? (Yes/No): "
    
    )
    
27. if
    
    user_input.lower
    
    (
    
    )
    
    ==
    
    'no'
    
    :
    
28. print
    
    (
    
    "Exit program."
    
    )
    
29. break
    
30. 
    
31. elif
    
    user_input.lower
    
    (
    
    )
    
    ==
    
    'yes'
    
    :
    
32. ret=
    
    True
    
33. 
    
34. else
    
    :
    
35. print
    
    (
    
    "Wrong input."
    
    )
    
36. ret=
    
    True
    
37. 
    
38. 
    
39. if
    
    ret:
    
40. continue
    

In the provided code, we simply enclosed the code with a while loop to allow for continuous execution of the program. We will create a method that will set the timer based on the input you provide. You just need to call the method in order to display the timer.
