Learn Python the way people actually write it in 2026: with an AI assistant beside you. Every chapter teaches one concept with runnable examples and their output, then gives you an exact prompt to paste into ChatGPT, Claude or Copilot so you practise, get explanations and fix mistakes faster. No prior programming experience needed.
What you will learn
Python fundamentals
Syntax, variables, data types, strings, collections, conditions, loops and functions, each with examples and output.

Who this course is for
Excel and Google Sheets users who want to automate reports, analysts moving into pandas and dashboards, students preparing for data roles, and anyone who has tried to learn Python before and stalled. If you can write a spreadsheet formula, you can follow chapter 1.
How to practise
- Install Python locally with VS Code (chapter 2), or
- use a free browser editor such as online-python.com or Google Colab while you decide, and
- keep an AI assistant open in a second tab for the practice prompts.
Prefer a finished dashboard?
Ready-made Excel, Google Sheets and Power BI templates from the same team are on NextGenTemplates.com, each with a video walkthrough.
Frequently asked questions
Is this Python course really free?
Yes. All 48 chapters are free to read with no sign-up. Practice files and code are included in the chapters.
Which Python version does it use?
Python 3.12 and later. Examples avoid features removed from Python 3 and note where libraries such as pandas 2.x behave differently.
Do I need to pay for an AI assistant?
No. The free tiers of ChatGPT, Claude and Copilot are enough for the practice prompts. The API chapters explain costs before you spend anything.
How long does it take?
About 25 hours in total. At one chapter a day you finish in seven weeks; the fundamentals (chapters 1 to 24) take about two weeks.
Is there a certificate?
Not for the free course. You finish with ten portfolio projects and a cheat sheet, which matter more in interviews.
