On Windows XP, using Python 2.6, 2.7, 3.3, or PyPy 2.2,

C:\Documents and Settings\pc40583>c:\python26\python
Python 2.6 (r26:66721, Oct  2 2008, 11:35:03) [MSC v.1500 32 bit
(Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import os
>>> print(os.path.expanduser('~'))
C:\Documents and Settings\pcock

i.e. As expected, it found my home directory.

Yes in theory, but in practice using the Unix style slashes works
just fine in my experience (and they are used in many of our
unit tests without problem). Even a mix of slashes works.

Note style-wise it would be preferable to use os.path.join(...)
rather than the string join method os.sep.join(...) as shown.
