Somehow that is still not clear?
Sorry Ben I misunderstood. I think I can see the source of confusion which is in your first message: """ In some code (e.g. unit tests) I am calling ‘tempfile.mktemp’ to generate a unique path for a filesystem entry that I *do not want* to exist on the real filesystem. """ I read that as meaning that it was important that the file did not exist. But you say that you don't care if the file actually exists in the filesystem or not and just want a unique path. What do you mean by unique here? The intention of mktemp is that the path is unique so that there would not exist a file of that name and if you opened it for writing you wouldn't be interfering with any existing file. Do you just mean a function that returns a different value each time it's called? How about this: count = 0 def unique_path(): global count count += 1 return os.path.join(tempfile.gettempdir(), str(count)) -- Oscar -- https://mail.python.org/mailman/listinfo/python-list
