# How to Convert Time to 24 Hour Time in Python

In this tutorial, we will program 'How to Convert Time to 24-Hour Format in Python.' We will learn how to convert AM/PM time to the 24-hour format. The objective is to convert 12-hour time into the 24-hour time format. 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.

## 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.
1. def convert24(str1):
2.
3.
4.         if str1[-2:] == "AM" and str1[:2] == "12":
5.                 return "00" + str1[2:-2]
6.
7.         elif str1[-2:] == "AM":
8.                 return str1[:-2]
9.
10.
11.         elif str1[-2:] == "PM" and str1[:2] == "12":
12.                 return str1[:-2]
13.
14.         else:
15.
16.                 return str(int(str1[:2]) + 12) + str1[2:8]
17.
18.
19. print("\n================== Convert Time to 24 Hour Time  ==================\n\n")
20.
21. print("Time is: ",convert24("10:15:00 PM"))

The convert24 function is designed to convert a 12-hour time format (with "AM" or "PM") to a 24-hour time format. However, there's a small issue in the else clause where the PM time is converted. The function attempts to convert the hour part of the time string from 12-hour format to 24-hour format but mistakenly concatenates the hour conversion as a string without correcting the rest of the time string.

## Output:

There you have it we successfully created How to Convert Time to 24 Hour Time 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!
