I don't understand this. Could you please elaborate? - if sys or os
are not imported for any other causes how are they already imported?
Maybe I'm wrong here, and accessing the filesystem and reading the
module into memory represents no cost. My mistake, in that case.

It may be lousy, but it requires no imports. And, as I said in the
answer to Steve, I _know_ there are many ways to achieve this,
including yours. But in your rush to pin-point lousy code, you didn't
read that, I suppose.
