1 · Your first notebook
Everything below is live — it’s a real Python notebook running in your browser. Click into the first code cell and press Shift + Enter to run it. Then keep going, cell by cell.
⏳ The first cell takes a few seconds while Python starts up in your browser. After that, everything is instant.
The DataLab's lessons were updated since your last visit, so this notebook now shows the new version. Your saved portfolio is not affected.
The notebook above runs entirely in your browser — nothing is installed and nothing leaves your device. Your changes are kept in this browser. First load takes a few seconds while Python starts.
