Python - Removing duplicates from a list

Learn how to efficiently remove duplicates from Python lists with our comprehensive guide. Explore effective techniques to streamline your coding and enhance data management skills in Python.

What is a Python list?

In Python, a list is a built-in data structure that is used to store collections of items. It is one of the most commonly used data structures in Python and is very versatile. Lists are mutable, meaning that their elements can be changed after the list is created. They can contain elements of different data types, including other lists.

How does a list work?

In Python, lists work as dynamic arrays, meaning they can be resized and can hold elements of different data types. Lists are ordered collections, meaning the order of elements is maintained. Elements can be accessed using indexes, starting from 0. Lists support various operations like appending, slicing, and sorting. They are mutable, allowing for easy modifications such as addition, deletion, and modification of elements.

Why use a list?

For efficient data organization and easy access, Python lists facilitate seamless management and retrieval of multiple related items within a single entity.

Python - Removing duplicates from a list

Create a Python list with duplicated entries.

Remove duplicated entries from a list.

This approach might not maintain the original order of the elements.

If the order of the elements is important, use an approach that preserves the original order.

Optionally, use the For loop to remove duplicates and preserve the original order.

Another way to remove duplicates and maintain the order of elements is to use the COLLECTIONS library.

Multiple ways to remove duplicate entries from a list in Python have been presented.
