String indexing and Slicing in Python
Introduction The Python string data type is a sequence made up of one or further individual characters that could correspond to letters, figures, whitespace characters, or symbols. As the string is a sequence, it can be penetrated in the same ways that other sequence-grounded data types are, through indexing and slicing. Indexing Indexing means pertaining to an element of an iterable by its position within the iterable. Each of a string’s characters corresponds to an indicator number and each character can be penetrated using their indicator number. We can pierce characters in a String in Two ways Penetrating Characters by Positive Indicator Number Penetrating Characters by Negative Indicator Number 1.
