As for what is relevant for the original question is that the ValueError exception is a practical trap that I have fallen into, and, as I demonstrated yesterday, the http.server module has fallen into (through os.path.isdir()). In fact, I couldn't spot a single instance of os.path.exists() in the Python standard library that would guard against a ValueError (to be sure, in almost all of the cases you could argue it would be redundant). Whatever your philosophical tastes, this unexpected feature of os.path.exists() (& co) leads to unexpected application behavior IRL, and, in the GhostBusters sense, that is bad.
