Every item must supply exactly two values.Ճիշտ պատասխան
Items must alternate between key and value.
Only dictionary keys may be visited.

Each visited item must provide exactly two values, one for key and one for value. The names do not take alternating iterations, and an item with the wrong number of values cannot be unpacked into this target shape.
