So maybe we need to add dict.ordered() which returns a view on the items that is a Sequence rather than a set? Or ordereditems(), orderedkeys() and orderedvalues()? On Fri, Jul 31, 2020 at 05:29 Ricky Teachey <ricky@teachey.org> wrote:

The punchline of Wes Turner's notebook (very well put together, thank you!) seems to partly be that if you find yourself wanting to work with the position of items in a dict, you might want to consider using a pandas.Series (with it's .iloc method).
A difficulty that immediately came to mind with this advice is type hinting support. I was just googling yesterday for "how to type hint using pandas" and the only thing I found is to use pd.Series and pd.DataFrame directly.
But those don't support type hinting comparable to:
Dict[str, float]
Or:
class Vector(TypedDict): i: float j: float
This is a big downside of the advice "just use pandas". Although I love using pandas and use it all the time.
