Submitted by razormist on Friday, December 27, 2024 - 23:51.

In this tutorial, we’ll learn how to program "How to Check If a List is Empty in Python." The objective is to determine whether a given list is empty. This tutorial will demonstrate the process of checking if a list is empty using straightforward and efficient methods. 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 check if a list is empty. 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.

while True:
    print("\n================= Check If a List is Empty =================\n\n")
 
    my_list = []
 
    print("Current List: ", my_list)
    
    if not my_list:
        print("the list is empty")
 
 
    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 program checks if a given list is empty. Initially, the list my_list is defined as empty ([]). The program then evaluates the condition if not my_list to determine whether the list is empty and displays an appropriate message. Users are prompted to repeat the process or exit the program based on their input.

Output:
