I think this is a bad solution, because you re-set the whole entry for key 1 again. Why not use the following?

people[1]['last_name'] = 'Dactill'

I agree it is bad practice.

If this was intended as update showcase:

people[1].update(last_name='Dactill')

I agree, it does seem somewhat counter-intuitive to pass the dictionary again associated with the first key as well as repeating the values. Programatically, this would also be more difficult to achieve. I shared that solution as I found it to be a bit more simpler.

I like this solution a lot, thank you for sharing! There are almost infinite possibilities of alternate ways to achieve our desired outcome. This one certainly would have been easier to understand with knowledge of indexing dictionaries. The update demonstration would have been much easier without a nested dictionary in this case.
