Introduction to Python Strings

Strings are a fundamental datatype in computer programming. They are used to represent text and other types of data that can be represented as a sequence of characters. In Python, we can create and manipulate strings using a variety of built-in functions and methods.

To create a string in Python, we simply enclose the text in single or double quotes:

In addition to indexing and slicing, Python provides a variety of string methods that allow us to manipulate strings in useful ways. For example, we can convert a string to uppercase or lowercase:
