Frequently asked questions

Is this Python playground free?+
Yes — it's completely free, runs in your browser, and needs no login or installation.
Does it run real Python?+
Yes. It runs real Python 3 in your browser using Pyodide (Python compiled to WebAssembly). Most standard-library code and print-based programs work. Some packages and file/network operations are limited in the browser.
Is this good for CBSE Class 12 Computer Science practice?+
It's great for practising Python syntax, loops, functions, strings, lists and logic quickly. For the full CBSE practical (with MySQL connectivity and file handling), Kwickprep's classes give you a proper setup and guidance.
Why does the first run take a few seconds?+
The first time you click Run, the browser downloads the Python engine (Pyodide). After that, runs are fast. Nothing is downloaded until you click Run, so the page loads instantly.
