Records and files

Store collections and work with files

Tuples, sets, and dictionaries provide different ways to organize data in Python. Tuples keep values in a fixed sequence, sets store distinct values, and dictionaries connect keys with values. Choose a collection according to how you need to store and access the data.

Files keep data available after a program finishes. This part also covers file paths, reading and writing data, and organizing files and folders.
