No complicated setup.
Just you, your browser, and a fresh start.
Start from the very beginning. Build confidence one concept at a time. No experience needed, and no rush to keep up. Finish a course and personalise your LearnLab completion certificate.
Your friendly first programming language. Analyse data, automate everyday work, build games and bring useful ideas to life.
Find the stories hiding in data. Filter, join, summarise and explore a sample business database, right inside your browser.
No wall of jargon. No racing ahead. Just a clear next step, a little practice, and that lovely “aha!” moment.
Data analyst? Game maker? Curious explorer? Pick a goal and a learning language that feels like you.
Simple explanations and small examples make every new concept easier to hold onto.
Run real code, solve a tiny challenge, then check your understanding with a quick quiz.
Try the challenge and quiz, or check the answer when you get stuck, then move forward. Return later and pick up where you left off.
Make a prediction. Press run. See what happens. Then take your ideas to the full practice editor, where the code is yours to change.

Simple answers, before you start.
Yes. All 64 lessons, the Python and SQL practice editors, quizzes and guided projects are free. There are no subscriptions or paid lesson unlocks. Free learning does not mean the website will always be advertising-free; clearly labelled ads may be added later.
No. Your completed lessons, learning language and goal are remembered in this browser using local storage. No login, email address or tracking cookie is needed.
Progress remains in the same browser while its stored data is kept. Clearing site data, using private browsing or moving to another device can remove it. Export a small progress backup from My progress to keep a copy.
Practice code stays only in memory for your current page session. Reloading, leaving the learning page or 15 minutes of inactivity clears it. SQL playground changes are temporary too. Only compact learning milestones are stored.
Each course follows a clear sequence. Try the current practice challenge and knowledge check, or choose Check answer to learn from a worked solution, then unlock the next lesson. You can revisit completed lessons or restart either course at any time.
Yes. The learning space adapts to desktop, tablet and mobile, with bottom navigation on small screens. You can add it to your Android or iPhone home screen. Python execution needs internet; visited course pages can work offline, and SQL can run offline after its first successful online run.
Practice uses SQLite in your browser. Core topics such as SELECT, JOIN, grouping and subqueries transfer to many SQL databases. Date functions, schema rules and some advanced syntax differ in MySQL, PostgreSQL and SQL Server.
Yes. Lesson explanations and practice instructions are available in English, Hindi and Hinglish. Code keywords stay in their original language. Some project instructions and technical terminology are in English.
Yes. Finish all 32 lessons in a course, then pass a short final test (20 questions, 70% to pass, unlimited retries). You then add your name and download an Excel Keys certificate as a PDF or image, with a certificate ID and your test score. You can add it to LinkedIn in one click. It recognises self-paced completion; it is not an accredited qualification. Following our social channels is optional.
You don't need to know everything. You just need a first step.
Excel Keys designs custom Excel and HTML dashboards around your own KPIs and Excel files. They run offline in the browser, so your data stays on your computer.
