Python, a versatile and widely-used programming language, supports various data types to handle different kinds of information. One fundamental and frequently used data type is the string. In Python, a string is a sequence of characters, and it is a crucial component for handling textual data.

Defining a String in Python

Defining a string in Python is straightforward. You can use either single quotes (') or double quotes ("). For example:
