Brett Cannon added the comment: The classes mentioned actually require that the path exist on the file system so there's no extra restrictions. As for cost, it's pretty cheap as a call to _os.fspath() is written in C and does an immediate type-check for str or bytes for the common-case (https://github.com/python/cpython/blob/master/Modules/posixmodule.c#L12099). These classes are also instantiated once typically and then cached so the cost is only paid once per object.
As for use-cases, I've seen people directly instantiate these classes in user code and so supporting paths in a universal way like the rest of the stdlib would be good for consistency. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue30247> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
