Why was Path.path added?
Well, it's already there and it's probably too late to remove it, but introducing the idiom path_str = getattr(arg, "path", arg) was not necessary: you could also write path_str = str(Path(arg)) which works just as well. My 2c., Antony

pathlib is provisional, so it *can* be removed (and indeed probably will be - see the endless threads here and on python-dev)
The latter requires you to import pathlib, which is not Python 2.7-compatible. A minor point, but one reason why the path attribute offers simpler code. Also, str(Path(arg)) applies an unnecessary call to Path() if arg is already a path. (And str(arg) is not OK, as it will also accept things like ints). If you want the full details, please read the various threads that have been going on here for about a month. It isn't worth reiterating the debate again, I'm afraid - most people are fairly burned out on pathlib discussions by now. Paul

A problem with .path, however, is that there should be only one way to do it, and if I were to decide, I would probably remove it in pathlib.PurePath before it's too late. -Koos

I think you meant "ceasing" the discussion -- but case that was intentional, I like it! it really did need to be seized! :-) -CHB -- Christopher Barker, Ph.D. Oceanographer Emergency Response Division NOAA/NOS/OR&R (206) 526-6959 voice 7600 Sand Point Way NE (206) 526-6329 fax Seattle, WA 98115 (206) 526-6317 main reception Chris.Barker@noaa.gov
