How should I check if I can create files in a directory?
So maybe the only solution that works is something like
try:
open(path.join('temp', 'w'))
except OsError:
return False
else:
os.remove(path.join('temp'))
return True
It depends on the system & location. It's possible to set up
directories with permissions that allow you to create files but not
delete them, in which case you'd either (1) create the file and
possibly fail on subsequent tests because the file already exists; or
(2) litter the directory with tmpnam()-like results that you were
unable to delete.
It's ugly, I've encountered it, and haven't found a good universal
solution myself.

That's really ugly right, didn't think about this possibility.
Well it's not a really critical part of my code, so I guess it's fine
with the try-except dance..
But isn't there (or should there be) a windows-related library that
abstracts this horrible things?
Well I maintain winsys [1] which does help out in admin-y tasks
in general on Windows, but I'm afraid I've never had the need
to scratch this particular itch, and the API solution is messier
than you might think, and more fiddly to get right. If I ever
get enough moments together I might do it, but patches are
always looked upon kindly :)
