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 unique, allowing you to quickly lookup specific information based on a meaningful identifier. Dictionaries are ideal for representing real-world associations, such as a student's identity and their corresponding marks.
- Python dictionaries are modifiable
- Traversing through dictionaries is common for processing data.
- Functions like inserting new key-value pairs and removing existing ones are essential for managing dictionaries.
