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

New submission from Lewis Ball : Currently the docs for `difflib.SequenceMatcher.quick_ratio()` just says 'Return an upper bound on ratio() relatively quickly', which doesn't give much of an idea about how that upper bound is calculated. `real_quick_ratio` has similarly brief documentation.

[issue40540] inconstent stdin buffering/seeking behaviour

New submission from Peter Law : `sys.stdin` (on Windows, tested Pythons 3.6-3.8) appears to have different seeking behaviour depending on the source of the incoming data. This seems arguably reasonable given that `stdin` isn't always seekable, however even in the failing case `sys.stdin.seeka

New submission from Raymond Hettinger : I've seen multiple requests for this and it isn't obvious how to do it with the existing tooling. The example currently given in the recipes section isn't scalable because it involves expanding the population into a big list with repeated elements:
