In this tutorial, we will program a 'How to Remove Duplicate Element From a List in Python'. We will gain a better understanding of checking whether a string is a number. The main goal here is to understand the structure of the program for checking the string. I will provide a sample program to demonstrate the actual coding of this tutorial.

This topic is very easy to understand; just follow the instructions I provide, and you can also do it yourself with ease. The program I will show you covers the basics of programming for removing duplicate element. I will do my best to provide you with the easiest method of creating this program, called 'Remove Duplicate Element'. So, let's start with the 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 removing duplicate element. To do this, simply copy and paste these blocks of code into the IDLE text editor.

while True:
    ret=False
 
    print("\n\n================= Remove Duplicate Element From a List =================\n\n")
 
 
        
    mylist = [1, 2, 2, 3, 4, 4, 5, 6]
 
    print("My List: ", mylist)
    print("\n")
    print("New List: ",list(set(mylist)))
        
    user_input=input("\n\nTry Again? (Yes/No): ")
    if user_input.lower()=='no':
        print("Exit program.")
        break
 
    elif user_input.lower()=='yes':
        ret=True
 
    else:
        print("Wrong input.")
        ret=True
 
 
    if ret:
        continue

In the provided code, to remove duplicate elements, we simply declare a set function abbreviation set() with the list we will be using.
