New submission from Victor Domingos <editor.arcosonl...@gmail.com>:
This method fails with an error when it finds a character or block device (like
those found in /dev on macOS). However, in the same machine, with the same
Python version, the alternative os.walk() performs basically the same job with
no errors. I am not sure if that error is the expected behaviour, but I wasn't
able to find a clear explanation in the docs. Anyway, it seems to me, as a
user, that the os.walk() error-less behaviour is more desirable.
