A dictionary in Python is an unordered collection of key-value pairs. It is a mutable, indexed, and iterable data structure that is commonly used to store and retrieve data. The keys in a dictionary must be unique and immutable (strings, integers, tuples) while the values can be of any data type (strings, integers, lists, sets, other dictionaries, etc.)
