But in some instance, there is more than one way to interpolate, so it would be great to have:
sea_surface_temp[-78.123, 28.432, interp='linear']
I presume you would only use this to get the temperature and not to set or delete measurements. Is that correct?
yes. working with this gridded data is pretty much a one-way street. If you want to change the values, you really need to work with the underlying arrays. Though now you mention it, I may think about that some more -- maybe there's something that could be done there? I haven't thought about it because I (nor any of my users) don't have a use case for that. -CHB
and that would require having mixed positional and keyword index parameters.

In this fashion have you considering having keyword only indices, that is to only allow either obj[1, 2] or obj[row=1, col=2] (if the class supports it), and disallow mixing positional and keyword indices, meaning obj[1, col=2] would be a SyntaxError.
That would severely reduce the usefulness of this feature for me, probably by 80 or 90%, and possibly make it useless for xarray and pandas.
(I don't speak for the pandas or xarray devs, I'm happy to be corrected.)
From my perspective as a developer for both xarray and pandas, both "mixed" and "keyword only" indexing have use cases, but I would guess keyword only indexing is more important.
In xarray, we currently have methods that awkwardly approximate keyword only indexing (e.g., xarray.DataArray.sel() and xarray.DataArray.isel() both allow for named dimensions with **kwargs), but nothing for the "mixed" case (neither method supports positional *args). _______________________________________________ Python-ideas mailing list -- python-ideas@python.org To unsubscribe send an email to python-ideas-leave@python.org https://mail.python.org/mailman3/lists/python-ideas.python.org/ Message archived at https://mail.python.org/archives/list/python-ideas@python.org/message/IPEP5Y...
