A dictionary in Python is an unordered collection of key-value pairs. It is a built-in data type that allows you to store and retrieve data using keys rather than indices like in lists or tuples. Each key in a dictionary must be unique and is associated with a corresponding value. Dictionaries are mutable, meaning you can add, delete, or modify key-value pairs. They are commonly used for tasks such as mapping, caching, and managing data with meaningful identifiers.
