Excel and other spreadsheet software products localize their function names.
So people learn to use those in their native language which is great.
But if they need to use the same software with a different language setting, because they move or work abroad, they have to relearn all those function names, which sucks...
It's not great even in the learning scenario. First I have to Google how to solve the problem and then I have to Google how to translate the function names to Swedish.
It's already there, I've often seen console output with translated error messages. Helpful for the users but not of much use to developers, unless using error codes as well
More like 'Haupt.py'. ('Haut' is 'skin') But in German that alone would translate back to 'head.py', so you might want to give some more context to it like 'Hauptdatei.py' ('main file.py').
