tempfile — Temporary File System Objects — PyMOTW 3
Creating temporary files with unique names securely, so they cannot be guessed by someone wanting to break the application or steal the data, is challenging. The tempfile module provides several functions for creating temporary file system resources securely. TemporaryFile() opens and returns an unnamed file, NamedTemporaryFile() opens and returns a named file, SpooledTemporaryFile holds its content in memory before writing to disk, and TemporaryDirectory is a context manager what removes the directory when the context is closed.
