Exercise 1 - Slicing the Lists

In Python, you can extract or retrieve the list items by providing the index numbers of the items. This process is known as slicing. You can also modify the list items as desired. The items in a list from left to right will have positive index numbers and from right to left will have negative index numbers. You can slice the list using negative index numbers also.

In this exercise, you will learn to write programs to perform the following tasks:

• Slice items in a list using positive index numbers.
• Modify the list items.
• Slice items in a list using negative index numbers.
