Dictionaries

Dictionaries in programming are data structures that store data as key-value pairs, similar to how words and definitions are organized in a real dictionary. Each key is a unique identifier used to access its associated value quickly. This setup allows for efficient data retrieval, modification, and management. For example, in a dictionary representing a person, keys might include "name," "age," and "email," with corresponding values like "Alice," 30, and "[email protected]." Dictionaries are versatile and widely used for tasks where quick lookup and organized storage of related information are needed.
