Bite-Size Python

8Lists

If you were asked to list all your friends in Python, you might think to create a variable for each friend and assign their name to the variable. However, you wouldn't be able to work with all friend variables easily in a program as you would have to remember the variable name for each individual friend and apply changes one by one. Python enables you to group related items together into a list, which provides you with a better experience to manipulate the collection of items.

Create a List

A list is a collection of items that are ordered and can be changed. This means that each item in the list has a specific position, and if you'd like to change the items in the list, you can do so. You can also have duplicate items in a list.

Let's create a list that consists of hobbies! Start with a variable hobbies and place each of your hobbies in the list as a string.

>>> hobbies = ['swimming', 'dancing', 'singing'] 

To print the list, use print() and pass in the hobbies variable. Python prints the entire list in order surrounded by brackets.

>>> hobbies = ['swimming', 'dancing', 'singing']
>>> print(hobbies)
['swimming', 'dancing', 'singing']
