[docs] [issue40539] Docs - difflib.SequenceMatcher quick_ratio and real_quick_ratio improved docs

Tim Peters added the comment: Thanks for the effort, but I'm rejecting this. The language deliberately defines nothing about how these are calculated. It defines how `.ratio()` is computed, but that's all. An implementation is free to do whatever it likes for the "quick" versions, provided only they return upper bounds on `.ratio()`. Indeed, it's perfectly fine if an implementation merely returns 1.0 for both, regardless of the arguments. If an implementation is cleverer than that, great, that's fine too - but it would be actively counterproductive to constrain them to be no _more_ clever than the current implementations. ---------- nosy: +tim.peters resolution: -> rejected stage: patch review -> resolved status: open -> closed _______________________________________ Python tracker https://bugs.python.org/issue40539 _______________________________________
