Part of the reason (I think) is that our CAD/Data Management system (which produces the aforementioned .MODEL files) substitutes (stupidly, IMNSHO) non-printable characters for embedded spaces in file names. This is part of what leads to my consternation here.
And yeah, Windows isn't helping matters much. No surprise there. :-P Just for s&g's, I ran this on python 2.3 on knoppix: >>> DIR = os.getcwd() >>> files = os.listdir(DIR) >>> file = files[-1] >>> print file L07JS41C.04389525AA.QTR±INR.E´C-P.D11.081305.P2.KPF.model >>> print repr(file) 'L07JS41C.04389525AA.QTR\xb1INR.E\xb4C-P.D11.081305.P2.KPF.model' >>> fullname = os.path.join(DIR, file) >>> print os.path.isfile(fullname) True <--- It works fine here >>> print os.path.isdir(fullname) False >>> files = os.listdir(unicode(DIR)) >>> file = files[-1] >>> print file L07JS41C.04389525AA.QTR±INR.E´C-P.D11.081305.P2.KPF.model >>> print repr(file) 'L07JS41C.04389525AA.QTR\xb1INR.E\xb4C-P.D11.081305.P2.KPF.model' >>> fullname = os.path.join(DIR, file) >>> print os.path.isfile(fullname) True <--- It works fine here too! >>> print os.path.isdir(fullname) False >>> This is when mounting the same samba share in Linux. This tends to support Tom's point re:the "non-roundtrippability" thing. Thanks again to all. -- http://mail.python.org/mailman/listinfo/python-list
