Meanwhile I'll write (a>b)-(a<b), which is what Python suggests after having removed cmp

  That works nicely too, for those languages with "1-0" booleans. For languages without them (Java, C# come to mind), the ternary is the next-best way.

  I mainly use Python but that would still be unclear to me. I think the ternary operator is the sweet spot between too verbose and too confusing.

  No, what Python suggests is just returning the value you sort on, or a tuple of the values to sort on. cmp() is deprecated because there is seldom reason to use it anymore. E.G: Sorting words according to their number of letter is just: sorted(words, key=len) You don't return 1, -1 or 0. If you want to rank participants of a game in a dictionary of scores using names as keys and points as values, you would to: sorted(scores.items(), key=lambda score: score[1]) Again you don't return 1, -1 or 0, just the value that is significant. It makes it very, very simple to reason about.

    Official docs: https://docs.python.org/3.0/whatsnew/3.0.html#ordering-comparisons https://docs.python.org/3.0/whatsnew/3.0.html#ordering-compa... > If you really need the cmp() functionality, you could use the expression (a > b) - (a < b) as the equivalent for cmp(a, b)
