Mastering Data Structures: Python Dictionaries Explained

Python dictionaries are flexible tools for storing and retrieving data. Unlike lists, which hold ordered collections of items, dictionaries use keys to access their values. Each key must be unique, allowing you to quickly fetch specific information based on a meaningful identifier. Dictionaries are ideal for representing real-world relationships, such as a student's profile and their corresponding grades.

• Python dictionaries are mutable
• Scanning through dictionaries is common for processing data.
• Methods like adding new key-value pairs and removing existing ones are essential for managing dictionaries.
