The Python random.choices() function defaults to selecting an item uniformly from the collection, but optionally lets you specify a list (of the same size) of weights to make a weighted sample instead. I suspect that'll be fairly useful.
(It also lets you instead specify your weights as cumulative weights; I dunno if we really need to support both. Converting one to the other is trivial.)
