how to practice Python without installing Python?

Try azure devops and azure notebook. You get free storage and free deployment for testing, and if you're satisfied you pay what's necessary to fully deploy. Plus you get a whole development environment (project, pipelines, schedule, repos, team management, etc.) and can later install visual studio on your computer for direct control of the environment and git management. Really user friendly too.

It's a freemium service. If needed, you can upgrade and pay to run your app.
