## Overview

This repository is a nine-chapter Python tutorial for data-focused developers, not a single application. The learner’s workflow is to study foundational object-oriented concepts, then explore concurrency, validation, APIs, testing, and operating-system file work, with practical examples along the way. The graph groups chapters by topic and highlights a few internal behaviors supported by sampled code. Most chapter links describe the curriculum documented in the README; sampled source confirms only the specific implementation relationships shown.

Main entry points: [`Ch-9_OS`](https://github.com/anshlambagit/python_advanced_course/tree/main/Ch-9_OS) (OS and files), [`Ch-1_OOP`](https://github.com/anshlambagit/python_advanced_course/tree/main/Ch-1_OOP) (OOP concepts), [`Ch-4_Multi-Threading`](https://github.com/anshlambagit/python_advanced_course/tree/main/Ch-4_Multi-Threading) (Threading), [`Ch-6_Async`](https://github.com/anshlambagit/python_advanced_course/tree/main/Ch-6_Async) (Async programming)
