Mastering Data Structures: Python Dictionaries Explained
Python dictionaries are powerful tools for storing and retrieving data. Unlike lists, which hold sequential collections of items, dictionaries use identifiers to access their values. Each key must be distinct, allowing you to quickly retrieve specific information based on a significant 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.
- Operations like appending new key-value pairs and clearing existing ones are essential for managing dictionaries.
