Chapter 9: Compound Data Types In the programming world, data is never isolated. We not only deal with individual numbers or strings but also manage a collection of data, such as a list of student grades, a set of coordinate points, or a collection of user tags. In Python, containers used to store multiple data … Read more
Lists Data items: do not need to have the same type Creation: Enclose different data items separated by commas in square brackets list1 = ['Google', 'Runoob', 1997, 2000] Indexing: starts from 0, the second index is 1, and so on.
