Remove Duplicates from a Python List

Removing duplicates from a Python list is one of the coding interview questions you may get to solve as a Python developer. So if you want to learn how to remove duplicate values from a Python list, this article is for you. In this article, I’ll walk you through how to write a program to remove duplicates from a Python list.

Remove Duplicates from a Python List

To remove duplicates from a Python list, we need to write an algorithm to remove duplicate values from the list. For example, let’s say a list of names of people repeats “Aman” more than once, so we have to write a program to remove “Aman” when it is found more than once in a list. So here’s how you can write a program to remove duplicate values from a Python list:

['Aman', 'Akanksha', 'Danish', 'Sajid']

There are many other ways to remove duplicate values from a Python list, but the algorithm I used is the most efficient you can use. In the code above, I started by defining a Python function that only accepts one parameter as a list of values. Then I introduced another Python list into the function. Then I used a for loop to retrieve unique values in the input list and store them in another list that I introduced inside the function.

Summary

So this is how you can write a program to remove duplicate values from a Python list. It is one of the coding interview questions you may get to solve as a Python developer.
