Reference notes

Python cleanup for quick snippets

Whitespace safe

The formatter expands tabs, trims trailing whitespace and keeps a final newline so snippets paste cleanly into editors.

Indentation aware

Basic checks flag mixed tabs/spaces, sudden indentation jumps and suspicious dedents before you copy the result.

Local processing

Code is handled by client-side JavaScript. Formalint does not run Python code or upload snippets to a server.
