How to Implement Bubble Sort in Python

Submitted by razormist on Tuesday, April 15, 2025 - 23:26.

In this tutorial, we’ll learn how to program "How to Implement Bubble Sort in Python." The objective is to safely implement a bubble sort on a dictionary. This tutorial will guide you through the process step by step, showing you how to perform sorting using the bubble sort algorithm. By the end, you’ll have a clear understanding of how to efficiently complete this task in Python.

This topic is straightforward to understand. Just follow the instructions I provide, and you’ll complete it with ease. The program I’ll demonstrate will show you the correct and efficient way to use bubble sort. So, let’s dive into the coding process!

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.

def bubble_sort(arr):  
    n = len(arr)  
  
    
    for i in range(n):  
         
        for j in range(0, n-i-1):  
            
            if arr[j] > arr[j+1]:  
                arr[j], arr[j+1] = arr[j+1], arr[j]  
  
 
if __name__ == "__main__":  
    while True:
        print("\n============= Implement Bubble Sort =============\n")
        my_list = [54, 33, 23, 12, 14, 8, 80]  
  
    
        print("Original List:", my_list)  
  
 
        bubble_sort(my_list)  
  
        print("Sorted List:", my_list)
 
        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 Python program demonstrates how to sort a list using the Bubble Sort algorithm. Inside a loop, the program initializes a predefined list of numbers and prints the original unsorted list. The bubble_sort function then performs sorting by repeatedly stepping through the list, comparing adjacent elements, and swapping them if they are in the wrong order.

This process is repeated for all elements, with each pass placing the next largest element in its correct position. After sorting, the program prints the sorted list. The user is prompted whether they want to run the process again, and based on the input, the loop continues or exits. This program is a good example of how basic sorting algorithms work and how user interaction can be handled in a loop.

Output:

There you have it we successfully created How to Implement Bubble Sort 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!
