New submission from Arno-Can Uestuensoez: I am currently finishing a file system library and use 'os.path.normpath' for canonical input into match-operations. So already found Issue26329 - IEEE-1003.1-Chap 4.2 and written a comment. But I guess this issue should be handled seperately. Now have to deal by myself with the eventual prefix 'file://' for input, and guess it should be supported. I did not found a statement on this case, so issue this for clarification. The 'os.path.normpath' call simply replaces subsequent os.sep, when they are not leading as 1003.1 states. But how should the following examples be handled: file:////a => /a OR //a ??? file://///a => /a OK file:///a => /a OK ---------- assignee: docs@python components: Documentation messages: 267407 nosy: Fred Rolland, Winterflower, acue, docs@python, ebarry, lemburg, serhiy.storchaka priority: normal severity: normal status: open title: just for clearing: os.path.normpath("file://a") returns "file:/a" type: behavior versions: Python 2.7 _______________________________________ Python tracker <report@bugs.python.org> <http://bugs.python.org/issue27228> _______________________________________
