I can, but it seems like the wrong usage of pattern matching and it requires much more code. ``` match m: case {"a": a, "b": b, **rest}: pass case _: raise ValueError ``` We can use pattern matching to unpack sequences, but we have special syntax for this: ``` s = range(1

[Python-ideas] Mapping unpacking assignment

I am proposing to add smth like JS destructing assignment to python. Basically, it will allow unpacking any mapping (should have __getitem__ and keys() methods) into variables. Proposed syntax: ``` m = {"a": 1, "b": 2, "c": 3, "d": 4} {a, b} = m # a: 1, b: 2 {a, b, **rest} = m # a: 1, b: 2, rest

Greetings, This library* seems to be used by many people for some treemap operations. Would it be a good idea to include it in upcoming versions? Leetcode has it by default for the lack of a similar something in Python. I did not check, but it seems other languages cater to structures better. * h
