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.
  1. while True:
  2.     ret=False
  3.  
  4.     print("\n\n================= Remove Duplicate Element From a List =================\n\n")
  5.  
  6.  
  7.        
  8.     mylist = [1, 2, 2, 3, 4, 4, 5, 6]
  9.  
  10.     print("My List: ", mylist)
  11.     print("\n")
  12.     print("New List: ",list(set(mylist)))
  13.        
  14.     user_input=input("\n\nTry Again? (Yes/No): ")
  15.     if user_input.lower()=='no':
  16.         print("Exit program.")
  17.         break
  18.  
  19.     elif user_input.lower()=='yes':
  20.         ret=True
  21.  
  22.     else:
  23.         print("Wrong input.")
  24.         ret=True
  25.  
  26.  
  27.     if ret:
  28.         continue

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