We can access an item in a list in Python using index notation. If we only know the value of the item in a list, we can use the index(~) method to locate its corresponding index position.

Examples

Access an element using index notation

Consider the following list:

letters = ['a', 'b', 'c']

We can print the second item in the list by:

print(letters[1])
b

Note that in Python, indexing starts at 0 and not 1. Therefore the first item in the letters list would be accessed by letters[0].

Locating index position

To locate the index position of element 'c':

letters.index('c')
2

Now we can retrieve 'c' from the list without initially knowing its index position:

letters[letters.index('c')]
'c'
