Learn web development with step-by-step guides
From beginner to advanced — Django, Python, REST APIs, JavaScript, Bootstrap, and more
Reproducible installs, fast CI, and shared internal libraries. Move from requirements.txt to pyproject and a lockfile, build wheels, publish to a private index, and stop hoping the build resolves the same twice.
Build production RPA bots in Python: log into vendor portals, scrape dashboards, fill forms, and persist sessions — orchestrated from Django via Celery. The modern, license-free alternative to UiPath and Automation Anywhere.
Move beyond "int and str" type hints. Master TypeVar generics, structural typing with Protocol, TypedDict for JSON, mypy strict mode, and runtime validation with pydantic v2 — what production codebases actually use.
Master async programming in Python. Learn event loops, coroutines, tasks, aiohttp for concurrent HTTP requests, and when async actually makes sense vs. threads or multiprocessing.
These tutorials are written from real production work, and the best ideas come from readers. Got a suggestion, a correction, or a subject you keep searching for and never find properly explained? Tell us — we read every message, and requested topics move to the front of the queue.
