[issue19844] os.path.split fails on windows path

2013-11-30 Thread Hanz Kanst 

New submission from Hanz Kanst:

os.path.split fails on windows path
to reproduce in python 3.3:

file = C:\progs\python\test\target\Amy Winehouse\Amy Winehouse - Back To Black 
(2006)\01 - Rehab.ogg
os.path.split(os.path.abspath(file))[0]
returns
'C:\\progs\\python\testordner\target\\Amy Winehouse'
and
os.path.split(os.path.abspath(file))[1]
returns
'Amy Winehouse - Back To Black (2006)\x01 - Rehab.ogg'

According to the definition the tail should never contain a tail.

SilentGhost added the comment:

file must be a raw string:

file = r'C:\progs\python'

Then everthing works.

Christian Heimes added the comment:

Ah, you fell victim to a classic gotcha. :)
Either you have to quote \ with \\ or you have to use a raw string. Withouth a 
raw string \t is TAB and \01 is the byte \x01:

 import ntpath
 fname = rC:\progs\python\test\target\Amy Winehouse\Amy Winehouse - Back To 
 Black (2006)\01 - Rehab.ogg
 ntpath.split(fname)
('C:\\progs\\python\\test\\target\\Amy Winehouse\\Amy Winehouse - Back To Black 
(2006)', '01 - Rehab.ogg')

 len(\01)
1
 \01 == chr(1)
True
 len(r\01)
3

Hanz Kanst added the comment:

Hm, how can I handle this if file is an existing string and there is no 
option to assign raw via r'some\raw\string'?

2013-11-30 Thread R. David Murray 

R. David Murray added the comment:

If it is an existing string, the backslashes are already in the string.  The r 
prefix or the escaping is only required to get the backslashes into a string 
when you are coding them into a source file.
