Exploring Data Structures: Python Dictionaries Explained
Python dictionaries are versatile tools for storing and retrieving data. Unlike lists, which hold sequential collections of items, dictionaries use indices to access their values. Each key must be unique, allowing you to quickly retrieve specific information based on a relevant identifier. Dictionaries are ideal for representing real-world mappings, such as a student's name and their corresponding scores.
- Python dictionaries are mutable
- Iteration through dictionaries is common for processing data.
- Functions like inserting new key-value pairs and clearing existing ones are essential for managing dictionaries.
