You Store Data and You Do Stuff With Data • The OOP Mindset

A beginner-friendly walkthrough of the OOP mindset in Python, using a market stall scenario to illustrate why classes and objects are useful. Starting from parallel lists, progressing through nested dictionaries, and finally arriving at a proper class definition, the post shows how OOP bundles data (via data attributes) and functionality (via methods) into a single self-contained unit. Key concepts covered include `__init__`, `self`, data attributes, and methods, with working code examples at each stage.
