Python courses

Python is the default language for both AI and backend in most modern stacks. These courses skip the variables-and-loops content and focus on the patterns engineers actually need: async/await for concurrency, Pydantic for typed data, Python for GenAI, and the integration patterns that tie it all together.

Common questions

Python: quick answers

  • Is Python 3.12+ assumed?

    Yes. All courses use 3.11 or newer, with modern syntax (match statements, improved typing, TaskGroups). 3.10 mostly works; anything older isn’t worth the retrofit.

  • Do I need async for LLM work?

    The moment you have parallel LLM calls, fan-out retrieval, or multiple providers, yes. The async-patterns course covers when sync is fine and when async starts paying off.

  • Pydantic v1 or v2?

    v2 everywhere. v2 is ~10× faster, has a cleaner validator API, and is the version every modern FastAPI install uses.

  • What about FastAPI?

    Covered as a separate skill track. If you’re building services, pair the Python courses with the FastAPI courses.

  • How deep does the Python-for-GenAI course go?

    Beginner-friendly to intermediate. It covers the Python subset AI work actually uses: types, async, context managers, generators, Pydantic. You don’t need to know metaclasses to ship production AI.
