We could provide several options though. a, b, c = **mapping a, b, **c = **mapping For the simple case. AND {"1": a, "foo.bar": b, **c} = **mapping For more complex cases. We already have suitabilities with regular unpacking such as: a, (b, c) = 1, range(2) The thing with those details is that you can completly ignore them, and don't know they exist, and simply look it up when you need it. But I must say: {"1": a, "foo.bar": b, **c} = **mapping Looks very ugly. Le 26/05/2016 07:48, Terry Reedy a écrit :

I agree that comprehensions plus tuple unpacking handle many possible use cases for dict unpacking.
There is another dict method that has been ignored in this discussion.
mapping = {'a': 1, 'b': 2, 'c': 3} x = mapping.pop('a') mapping {'c': 3, 'b': 2}
We have both subscripting and popping to handle getting a value and either leaving or removing the pair.
