Submitted by razormist on Monday, August 12, 2024 - 23:42.

In this tutorial, we will program 'How to Create a Lap Timer in Python.' We will learn how to display a lap timer in the console terminal. The objective is to create a lap timer program. I will provide a sample program to demonstrate the actual coding process in this tutorial.

This topic is very easy to understand. Just follow the instructions I provide, and you will be able to do it yourself with ease. The program I will show you covers the basics of programming for creating a lap timer. I will do my best to provide you with a simple method for starting a lap timer. 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 program. To do this, simply copy and paste these blocks of code into the IDLE text editor.

import time
 
 
starttime = time.time()
lasttime = starttime
lapnum = 1
 
ret = False
 
 
while True:
        print("\n================== Lap Timer ==================\n\n")
 
 
        print("Press ENTER to count laps.\nPress CTRL+C to stop")
 
        try:
                while True:
 
                        input()
 
                        laptime = round((time.time() - lasttime), 2)
 
        
                        totaltime = round((time.time() - starttime), 2)
 
                
                        print("Lap No. "+str(lapnum))
                        print("Total Time: "+str(totaltime))
                        print("Lap Time: "+str(laptime))
 
                        print("*"*20)
 
        
                        lasttime = time.time()
                        lapnum += 1
 
        except KeyboardInterrupt:
                print("Done")
 
        opt = input("\nDo you want to try again?(yes/no): ")
 
        if opt.lower() == 'yes':
                ret=False
        elif opt.lower() == 'no':
                ret=True
                print("Exiting program....")
 
        else:
                print("Please enter yes/no:")
                break
 
        if ret == False:
                continue

This script is a simple lap timer that allows the user to measure the time between laps and the total time elapsed. The user can start a new lap by pressing ENTER and stop the timer by pressing CTRL+C. After stopping, the user is asked if they want to restart the timer or exit the program.

Output:

There you have it we successfully created How to Create a Lap Timer in Python. I hope that this simple tutorial help you to what you are looking for. For more updates and tutorials just kindly visit this site. Enjoy Coding!
