in python2, dict.values() and dict.keys() return lists. but in python3, they return views, which cannot be indexed directly using an integer index. there are three use cases when we access these views in python3: 1. get the first element 2. get all the elements and then *might* want to access them by index 3. get the first element assuming there is only a single element in the view 4. iterate thru the view in the 1st case, we cannot assume the number of elements, so to be python3 compatible, we should use `next(iter(a_dict))` instead. in the 2nd case, in this change, the view is materialized using `list(a_dict)`. in the 3rd case, we can just continue using the short hand of ```py (first_element,) = a_dict.keys() ``` to unpack the view. this works in both python2 and python3. in the 4th case, the existing code works in both python2 and python3, as both list and view can be iterated using `iter`, and `len` works as well.
