Negative indexing usually starts where the array ends which is suppoted by python
Negative Index is starting/reading an array inrevrese, from finish to start.
In python the negitive number is used to start slicing from the end for example
favorite_food = ['rice',chicken','bread']
print(favorite_food[-1])
the result will be : bread .
It's reading data from last to first.
Positive Indexing
...
[0,1,2,3,...,a,b,c]
...-3-2-1
Negative Indexing
It is basically accessing index values in reverse order.
for eg: A list stores 5 integers then basically we access it with positive index i.e; list[1] or list[2] etc.
but if we aim to access numbers from back of list then we do it as i.e; list[-1] will give the last element of the list.
Negative indexing works same like general indexing the main difference is it starts from behind/end.
[0,1,2] General
[-2,-1,0] negative index
Thank You
Negative index starting with-1 and positive index start 0.Python supports negative indexing, which typically starts where the array ends.
Negative indexing in Python refers to accessing elements in a sequence using negative numbers as indices.
In Python, negative indexing is a feature that allows you to access elements in a sequence, such as a string, list, or tuple, from the end instead of the beginning. It provides a way to conveniently access elements relative to the end of the sequence without having to know its length.
Negative indexing is achieved by using negative numbers as indices. In Python, the index -1 refers to the last element, -2 refers to the second-to-last element, and so on. Here's an example to illustrate negative indexing:
Example:
In the example above, my_list[-1] returns the last element of the list (5), and my_list[-2] returns the second-to-last element (4).
Negative indexing can be particularly useful when you need to access elements in reverse order or when you don't know the length of the sequence in advance. It provides a convenient way to access elements from the end without explicitly calculating the index based on the length of the sequence.
Negative indexing in Python means the indexing starts from the end of the iterable to manipulate sequence objects such as lists, arrays, strings.
