Strings in Python are sequences of characters and are among the most widely used data types.

Strings are immutable, which means that once a string is created, its characters cannot be modified directly. This property ensures that strings can be passed around safely in a program without altering the original data. Python treats single characters as strings of length one, making it consistent in handling textual data. Various operations such as slicing, concatenating, and formatting are available, allowing for robust manipulation of text data.
