How fast is the execution?

After the initial Pyodide load (a few seconds on first visit), code execution is near-instant. The status bar shows exact execution time in milliseconds.

Can I run scripts with multiple files?

Yes. The IDE supports multiple file tabs. Create new files and switch between them while coding.
