Python: Print to Production

A complete path through Python — from your very first print("Hello") to production-ready code. Covers core language fundamentals, intermediate patterns (decorators, generators, context managers), concurrency and type hints, building production APIs with FastAPI, applying Python to ML/AI with NumPy/Pandas/scikit-learn, and a bonus phase on CPython internals — bytecode, the object model, descriptors, metaclasses, and the import system.

prerequisites

  • No programming experience required — we start from installing Python
  • A willingness to type code out and run it, not just read it

you'll learn

  • Write idiomatic Python — from variables and control flow to classes and decorators
  • Use comprehensions, generators, and context managers the way experienced Python developers do
  • Understand concurrency in Python: threading, multiprocessing, and asyncio — and when to reach for each
  • Add type hints and mypy checking to a codebase without giving up Python's dynamism
  • Build production APIs with FastAPI — routing, Pydantic validation, auth, databases, and background tasks
  • Apply Python to ML/AI with NumPy, Pandas, Matplotlib/Seaborn, and scikit-learn pipelines
  • Go under the hood — CPython bytecode, the object model, descriptors, metaclasses, and the import system

course structure

Phase 3 has a few gaps in the middle (dataclasses, memory management, and testing) that aren't written yet — everything else, including the FastAPI, ML/AI, and CPython Internals phases, is complete and ready to go.
