Python’s standard library is vast, providing ready-made tools for math, random numbers, and system interactions. Learn how to import and utilize modules like math, datetime, and os to avoid reinventing the wheel.

Why write code from scratch when you can extend functionality that already exists? We’ll explore inheritance to create specialized child classes that retain the features of their parent classes.

Not all methods act on individual objects; some belong to the class as a whole. Distinguish between instance methods that modify specific data and class methods that manage shared state.

Object-Oriented Programming (OOP) helps organize code by modeling real-world entities. We’ll break down the concept of Classes as blueprints and Objects as the specific houses built from those blueprints.

Modern applications exchange data using JSON, and Python’s built-in library handles this format seamlessly. Learn to serialize Python objects into JSON strings and deserialize them back for easy data storage and transfer.
