[New-bugs-announce] [issue33968] os.makedirs and empty string

[Carl Andersson]

New submission from Carl Andersson <carl.ande at icloud.com>:

os.makedirs does not handle the empty string the same way as the os.path.XX functions does. This is (to me) unexpected behaviour, since calls like `os.makedirs(os.path.dirname(filename), exist_ok=True)` raises an exception if `filename` does not contain any directories.
Also, it raises an `FileNotFoundError` regardless of the `exist_ok` flag. I would expect `os.makedirs('')` to fail with `FileExistsError` and `os.makedirs('', exist_ok=True)` to not do anything.
