robotidy screws up the syntax in python files

[DetachHead]

before:

def foo() -> None:
    if True:
        ...

command:

robotidy main.py

after:

def foo() -> None:
    if True:
...

i think robotidy should throw an error when you attempt to run it on a python file.

use case: i have vscode configured to run robotidy when saving .robot files, however there seems to be an issue with the extension i use where it sometimes attempts to run it on the wrong file (Gruntfuggly/triggertaskonsave#24), which means robotidy sometimes incorrectly runs on .py files

Thanks for the report - yeah it's not expected behaviour. You already found the place where robotidy takes care of paths in your attached PR -> we should update logic here so files provided from cli are also checked against our exclude/include options.
