Dictionaries and sets are powerful and versatile from "summary" of Fluent Python by Luciano Ramalho
Dictionaries and sets are fundamental data structures in Python that are widely used due to their versatility and efficiency. Dictionaries, also known as mappings, allow you to store key-value pairs, making it easy to retrieve values based on their associated keys. This simplicity and intuitive nature of dictionaries make them a powerful tool for many programming tasks. Sets, on the other hand, are collections of unique elements with no specific order. They are particularly useful for tasks that involve testing membership, eliminating duplicates, and performing set operations such as union, intersection, and difference. The efficiency of sets in these operations makes them a versatile choice for many applications. One key feature of...
