ALT Infographic titled “Read & Write JSON Files in Python.” It shows two main sections: (1) writing Python objects (dict with name, age, skills, active) to a JSON file using json.dump, and (2) reading JSON back into Python objects using json.load. Each section includes code snippets, method explanations, and sample output. A middle diagram visualizes conversion flow: Python object → JSON file → Python object. Bottom sections include quick tips (use UTF-8, indent for readability, supported types) and common patterns like json.dump() and json.load() usage.

ALT Infographic titled “OOP Concepts Using the House Example.” It explains encapsulation, inheritance, abstraction, and polymorphism with a house analogy. Left side defines each concept: encapsulation (hidden data like wiring), inheritance (SmartHouse is a type of House), abstraction (using a thermostat without knowing internals), and polymorphism (same action, different results). Center shows a class diagram: an abstract House class with address and private price, plus methods (set/get price, abstract build). SmartHouse and WoodenHouse inherit from House and implement build() and open_door() differently. Right side demonstrates polymorphism with code calling open_door() on different house types, showing different behaviors. Bottom summarizes how these concepts create flexible, reusable code.
