Lists

If you understand strings, you will easily understand Lists. A “list” in programming is a list of elements. See the example given below, showing a list of numbers.

Creating a List

Exercise: Define a List and print its value

>>> gifts = ['toys', 'clothes', 'jewellery', 'flower vase', 'bed sheets']

>>> gifts

['toys', 'clothes', 'jewellery', 'flower vase', 'bed sheets']

>>>

Lists are enclosed in square brackets and as in case of Strings, we can make use of index or position to know which element is at which index.
