os.path and Windows UNC paths

[Tim Howarth]

I've been trying to use os.path.exists and  os.path.isdir on
Windows(2000) UNC paths with Python 2.2 but it doesn't seem to behanve
sensibly.

os.path.isdir('\\\\server\\share') returns negative result when
os.path.listdir('\\\\server\\share') produces a dir listing.

Checking groups.google and the Python faq I found

8.6 Why does o.path.isdir() failon NT shared directories

Which implies it should work if a tralling '\\' is added

but

os.path.isdir('\\\\server\\share\\') still returns negative result

However  os.path.isdir('\\\\server\\share\\\\') returns true.

Is this sensible/to be trusted.

As an aside;

using os.path.isdir(r'\\server\share\') results in a complaint of
invalid token - I thought the r prefix meant use raw string, so why the
error ?
