New submission from John Jefferies:
I'm having trouble with a raw string of r'\\?\' as in the following session:
----------------
>>> a = r'\\?\'
File "<stdin>", line 1
a = r'\\?\'
^
SyntaxError: EOL while scanning string literal
----------------
which seems like a bug to me. I see the same behaviour in v3.3, v3.2, and v2.6.
I have tried searching for such a bug but search engines don't work well with a
string of non-alphanumerics.
Why is this string important? It's because the Win32 API functions throw an
error with path names longer than 260 chars unless the path names are prefixed
with this string, e.g:
shutil.copy2(r'\\?\C:\some\quite\long\path\name', dstname)
shutil.copy2(r'\\?\' + r'C:\some\quite\long\path\name', dstname)
where the first example throws an exception without the path name prefix; while
the second example fails to compile.
FTR. I can create the desired string in various other ways:
----------------
>>> a = '\\\\?\\'
>>> a
'\\\\?\\'
>>> a = r'\\?\ '[0:4]
>>> a
'\\\\?\\'
>>>
----------------
Thanks
John
