How to Make a List in Python

Guide Kit

A list is a data structure in Python that houses an ordered group of things. Lists are created by placing a sequence of items inside square brackets [], separated by commas. Lists in Python are mutable, meaning the elements inside a list can be changed after the list is created. You can add, remove, or modify elements in a list using various built-in methods such as list.append(), list.extend(), list.insert(), list.remove(), list.pop(), etc. 

In Python, we may make a list of ints, strings, or mixed data types. We may also make a list that is empty. Other ways are: 

Creating a list with the “list()” function. 
list(): In Python, a list function is a built-in function used to perform operations on a list. 
Creating a list with the “range()” function. 
range(): In Python, the range() function is a built-in function that generates a sequence of numbers.

You can also create a list using list comprehension, a concise way to create a list by applying a transformation to each element in an existing list or iterable. Remember that list is an ordered collection, so the order of items will always be the same as if it was added. 

Please review the code below to learn more about creating a list in python.
