I think you have missed the point of your own thread. You can't do what you wanted using tempfile, the only possible answer is to choose a filename that is sufficiently random that your hope that it is unique won't be proven futile. tempfile has two main modes, mktemp which meets your requirements but should never be used as it is insecure, and mkstemp which doesn't meet your requirements because it fundamentally operates by actually creating the file in question and relying on the filesystem to guarantee uniqueness. -- https://mail.python.org/mailman/listinfo/python-list
