[issue39374] Key in sort -> Callable Object instead of function

[Raymond Hettinger]

Raymond Hettinger <raymond.hettinger at gmail.com> added the comment:

Go ahead and make a PR for this:

   function -> function (or other callable)

Let's keep the word "function" because it does a much better job of communicating that an the more abstract word "callable".
