Run Python Script

Run Python Script

Launch any local .py as a subprocess to visually preview its UI — without importing it into the project.

Launch

File → Run Python Script… or the toolbar entry. Pick a .py / .pyw file.

What it does

Spawns a fresh Python process running that file. The script's window opens alongside the builder. Editor state is untouched.

What it is not

This does not parse the script or turn it into widgets. For that, see Python Import.
