What is a negative index in python?
Answer / chaitanya
Python arrays & list items can be accessed with positive or negative numbers (also known as index).
For instance our array/list is of size n, then for positive index 0 is the first index, 1 second, last index will be n-1. For negative index, -n is the first index, -(n-1) second, last negative index will be – 1.
A negative index accesses elements from the end of the list counting backwards.
An example to show negative index in python
>>> import array
>>> a= [1, 2, 3]
>>> print a[-3]
1
>>> print a[-2]
2
>>> print a[-1]
3
