Introducing Lists


A list is a collection of items in a particular order. You can make a list that includes the letters of the alphabet, the digits from 0–9, or the names of all the people in your family. You can put anything you want into a list, and the items in your list don’t have to be related in any particular way.
In Python, square brackets ([]) indicate a list, and individual elements
in the list are separated by commas.

For example:

names = ['james', 'connor', 'jacob', 'bella']
print(names)

The output will be:

['james', 'connor', 'jacob', 'bella']

Accessing Elements in a List


Lists are ordered collections, so you can access any element in a list by
telling Python the position, or index, of the item desired.

 names = ['james', 'connor', 'jacob', 'bella']
print(name[0])

The output will be:
james
Lists start from 0, so james is 0, connor is 1, jacob is 2, bella is 3.

You can also use strings methods on lists, for example:

names = ['james', 'connor', 'jacob', 'bella']
print(names[0].title())

The output will be:
James

Python has a special syntax for accessing the last item.

names = ['james', 'connor', 'jacob', 'bella']
print(names[-1])

The result will be the following:
bella
