The issue that I raised here was whether the behaviour of os.path.join() in treating the Windows directory separator '\\' as an absolute path should be considered a bug. The behaviour of join came up for me when I tried to use the os.path functions to create a path that could only ever be used as a directory and never a file. The only way that I found to designate a path as a directory path was to add '\\' at the end. But this doesn't work in using os.path becaause the other os.path functions just strip it off and turn the directories back into files. I had hoped that join's documented use of an empty final parameter to add '\\' might behave differently but it gets stripped off as well :-( I thought that the description of pathlib behaviour above suported the view that the os.path.joing behaviour is a bug, and in a sense it does, but more importantly it an indication that pathib, not os.path, should be the module of choice for anyone who spends a lot of time manipulating paths on Windows. -- https://mail.python.org/mailman/listinfo/python-list
