Python for AI Engineering

A beginner-first, project-based path that takes you from installing Python to writing the kind of Python that AI engineering runs on. No computer-science background required: every day explains the idea in plain English, builds one small working project, and runs entirely on your own laptop (macOS, Linux or Windows). You finish able to handle data the Pythonic way, write typed and validated code, call APIs and LLMs asynchronously, and use NumPy and Pandas — the exact foundation needed before PyTorch, TensorFlow and Hugging Face.

01Setup & Python Basics

Install Python on any OS and write your first program, then master variables, collections, control flow, functions and modules.

02Pythonic Data Handling

Comprehensions, nested JSON-style data, and sorting, filtering, mapping and reducing — the everyday data moves of real Python.

0/0

    03Object-Oriented Python

    Classes and objects, inheritance versus composition, dataclasses, and when OOP actually pays off in AI and backend code.

      04Robust Code: Errors, Logging & Files

      Handle failures with exceptions and clean messages, add logging and debug confidently, and read and write text, JSON and .env files.

      0/0

        05Environments & Project Structure

        Virtual environments, pip and a clean project layout so every project is isolated and reproducible.

        0/0

          06Type Safety

          Type hints and static checking, then Pydantic models for validating the data flowing in and out of your programs.

          0/0

            07Async Python

            async/await, coroutines and concurrency — and exactly where async matters in LLM, RAG and agent applications.

            0/0

              08Python for APIs

              HTTP from a Python view, calling APIs with requests and async httpx, handling keys securely, and parsing and validating responses.

              0/0

                09Python for AI Workflows

                Call Claude, OpenAI and Gemini-style APIs, structure prompts and responses, parse structured outputs, and ship a real CLI AI tool.

                  10Data & ML Foundations

                  NumPy and tensor intuition, Pandas and datasets, plotting and inspection — why these come before PyTorch, TensorFlow and Hugging Face.
