[issue19161] collections Counter handles nan strangely

New submission from Adam Davison: If you pass an array containing nan to collections.Counter, rather than counting the number of 'nan's it outputs "'nan': 1" n times into the dictionary. I appreciate using this on an array of floats is a bit of an unusual case but I don't think this is the exp

[issue19161] collections Counter handles nan strangely

Mark Dickinson added the comment: > Presumably this relates to the fact that nan != nan. Yep. What you're seeing is pretty much expected behaviour, and it matches how NaNs behave with respect to containment in other Python contexts: >>> x = float('nan') >>> y = float('nan') >>> s = {x} >>> x
