Submitted by razormist on Monday, October 7, 2024 - 23:31.

In this tutorial, we will program "How to Remove Empty Lists from a List in Python." We will learn how to remove empty lists from a list. The objective is to safely identify and delete any empty lists within a list structure. I will provide a sample program to demonstrate the coding process in this tutorial.

This topic is very easy to understand. Just follow the instructions I provide, and you'll be able to do it yourself with ease. The program I’ll show you demonstrates the proper way of creatin an inverted star pattern. I'll do my best to provide a simple method for achieving this. 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.

ret = False
 
while True:
    print("\n================= Remove Empy List from a List =================\n\n")
 
    my_list = [4, 7, [], [], 10, [], [], 15]
 
    print("The original list is : " + str(my_list))
 
    res = list(filter(None, my_list))
 
    print("\nList after empty list removal : " + str(res))
 
    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 script removes empty lists from a given list using the filter() function. It processes a predefined list my_list, filters out the empty lists, and returns the updated list res. The program then displays both the original list and the list after empty list removal. Afterward, the user is prompted to try again or exit the program, and the loop continues until the user decides to stop.

Output:
