escaping

There are times that I automagically create small shell scripts from Python, and I want to make sure that the filename arguments do not contain non-escaped special characters. I've rolled my own solution, that I will provide as an answer, but I am almost certain I've seen such a function lost somewhere in the standard library. By “lost” I mean I didn't find it in an obvious module like shlex, cmd or subprocess.

Do you know of such a function in the stdlib?
