Python Examples - A Curated Collection

Abstract

A curated collection of practical Python code examples covering modern LLM integrations, web APIs, data processing, security tools, web scraping, and file manipulation. Each example is production-ready with proper error handling, security considerations, and clear documentation. Built by a developer who automates everything and believes good examples are better than lengthy tutorials.
