Hi,

A list in computer is an ordered data structure with a number of elements that are separated by a comma and are enclosed within square brackets .  For example, list1 and list2 below contains a single type of data. Here, list1 has integers while list2 has strings. Lists can also store mixed data types as shown in the list3 here.

List 1- [1,2,3,4,5]

List 2- [ 'Python', 'Java', 'C++']

List 3- [1, 'Python', 2, 'Java', 3]

I hope this helps,

All the best
