About this playground: privacy, safety and limits

Real Python. Your code runs in real Python (CPython via Pyodide) inside your browser, in a separate background worker so the page never freezes. Nothing you type is sent to a server.

Internet. The first visit downloads Python (about 12 MB) from this website. After that, your browser usually keeps a copy. It isn't guaranteed to work offline.

Included. The Python standard library: math, random, statistics, json, csv, datetime and more. Files you create live in memory and disappear when you reload. Packages such as numpy, pandas and scikit-learn aren't loaded.

Safety. Programs are stopped after a time limit or if they print too much. Student code can't import the browser bridge (js, pyodide), and the worker's network features are switched off before your code runs. These protections reduce risk, but no browser-side sandbox can guarantee complete security.

Your progress is saved only in this browser, on this device, if saving is switched on (see My progress). No names, accounts or personal information are collected.
