Detailed explanation-1: -Python also allows you to index from the end of the list using a negative number, where [-1] returns the last element. This is super-useful since it means you don’t have to programmatically find out the length of the iterable in order to work with elements at the end of it.

Detailed explanation-2: -From left to right, the index number starts from 0. From right to left (counting backwards), the index starts with-1. Accessing an element: Like with strings, enclose the index number with square brackets to access a list item, like lst[i] .

Detailed explanation-3: -In Python, indexing refers to the process of accessing a specific element in a sequence, such as a string or list, using its position or index number. Indexing in Python starts at 0, which means that the first element in a sequence has an index of 0, the second element has an index of 1, and so on.
