From 473106fee1ec4fcc9e2dde55c821effcd34e8a97 Mon Sep 17 00:00:00 2001 From: Ian Cordasco Date: Fri, 22 Jul 2016 17:02:12 -0500 Subject: [PATCH] Check for both os.path.sep and os.path.altsep When normalizing paths, we want to handle the following cases: - Someone is using a Windows-style path on Windows - Someone is using a Unix style path on Unix - Someone is using a Unix style path on Windows os.path.sep will handle the native directory separator character while os.path.altsep (when set) will handle alternate separators. Further, os.path.abspath does the right thing on Windows when handed a Unix-style path.
