Exercise 1 - Working with Lists

A list is a data structure in Python that can store an ordered sequence of related elements. Think about your song playlist, your emails, or any such collections of items you have.

Clearly, lists are useful when you want to keep related data together and work on it as a set. They help you perform the same methods and operations on multiple values at once, thereby helping you to condense your code. For example, all student names in the class could be stored as a list. Once done, you could print the complete list of student names all at once.

Each element or value that is inside of a list is called an item. As an ordered sequence of elements, each item in a list can be called individually, through indexing.

Internally, lists can be thought of as a compound data type made up of smaller parts. They are very flexible and enable individual items to be added, removed, and changed.

In this exercise, you will learn to write programs to create and print lists. You will also learn to access individual elements from a list and print them.
