A Python string is a sequence of characters enclosed within single, double, or triple quotes. Strings are immutable, meaning once defined, they cannot be changed.
Python provides a variety of methods for string manipulation, including concatenation (+), repetition (*), slicing, and built-in functions like len(), str(), and format().
Common string methods include lower(), upper(), strip(), replace(), and split(). Strings support indexing and slicing to access specific characters or substrings.
Python also allows for f-strings, which enable embedded expressions for formatting. Strings are widely used in text processing, data manipulation, and user interaction, making them a fundamental aspect of Python programming.
