In this tutorial, we’ll learn how to program "How to Concatenate Two Lists in Python." The objective is to safely merge two lists into a new, combined list. This tutorial will demonstrate the process of using concatenation to achieve the merging of lists effectively. A sample program will be provided to guide you through the implementation. So, let’s get started!

This topic is simple to understand. Just follow the instructions I provide, and you’ll be able to complete it with ease. The program I’ll demonstrate will show you the correct way to concatenate two list. I’ll also include a straightforward and efficient method to achieve this effectively. So, let’s start 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.
  1. list_1 = [1, 'a', 2]
  2. list_2 = [3, 4, 'b']
  3.  
  4. while True:
  5.     print("\n================= Concatenate Two List =================\n\n")
  6.  
  7.     list_joined = list_1 + list_2
  8.  
  9.     print("List 1: ", list_1)
  10.    
  11.     print("\nList 2: ", list_2)
  12.  
  13.     print("\nNew List: ",list_joined)
  14.  
  15.     opt = input("\nDo you want to try again?(yes/no): ")
  16.  
  17.     if opt.lower() == 'yes':
  18.         ret=False
  19.     elif opt.lower() == 'no':
  20.         ret=True
  21.         print("Exiting program....")
  22.     else:
  23.         print("Please enter yes/no:")
  24.         break
  25.  
  26.     if ret == False:
  27.         continue

This program demonstrates how to concatenate two lists in Python. The predefined list_1 contains [1, 'a', 2], and list_2 contains [3, 4, 'b']. By using the + operator, it creates a new combined list list_joined. The program displays the original lists and the concatenated result. Users can choose to repeat the operation or exit the program based on their input.

Output:

There you have it we successfully created How to Concatenate Two List 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!
