About Course

Have you ever wondered how apps like ChatGPT and Claude actually work, and whether you could build one yourself? In this course you will. Step by step, you’ll write Python code that talks to real AI models and turn it into your own AI assistant app that runs in a web browser.

This course is made for absolute beginners. If you finished Python for Absolute Beginners, you already know everything you need to start. Each lesson explains one idea in plain language, shows you working examples, lets you try it right on the page, and ends with a hands-on exercise and a practice file. That way you always know when you’ve got it.

You’ll start with OpenAI, then add Anthropic’s Claude, so you learn skills that work with more than one AI provider. By the end you’ll have a finished app with its own personality, a memory of the conversation, saved chats and a simple web interface, and you’ll be able to share it with friends.

What Will I Learn?

  • How AI apps work: models, prompts, APIs and API keys, explained simply
  • How to keep your API keys safe and control what you spend
  • How to send prompts to OpenAI and Anthropic Claude from Python
  • How to write prompts and system messages that get better answers
  • How to build a chat program that remembers the conversation
  • How to handle errors so your app doesn’t crash
  • How to write one function that works with either AI provider
  • How to save and load conversations
  • How to give your app a web interface with Streamlit
  • How to share your finished app online safely

Targeted Audience

  • Beginners who have finished Python for Absolute Beginners
  • Anyone who knows basic Python and wants to build something real with AI
  • Curious learners, students and professionals who want to understand how AI apps work by building one
  • No AI, web development or math background needed

Total Course Duration

About 12 hours (estimate, so adjust once the lessons are recorded)

Materials Included

  • Narrated slide videos for every lesson
  • Interactive “Try it” widgets inside each lesson
  • A downloadable practice file for every hands-on lesson, with a clear “You’re done when…” check
  • A quiz at the end of every lesson
  • A final project checklist and final quiz
  • Certificate of completion

Requirements/Instructions

  • Completion of Python for Absolute Beginners, or comfort with variables, input(), if/else, loops, functions, lists, dictionaries and files
  • A computer (Windows, Mac or Linux) with Python 3 installed
  • A code editor (VS Code recommended) and access to a terminal
  • An OpenAI account and an Anthropic account with a small amount of prepaid API credit (a few dollars is usually enough for the whole course)
