[Numpy-discussion] GitHub codespace is now available for numpy/numpy

[Inessa Pawson]

A GitHub codespace is now available for numpy/numpy.
Refer to the GitHub documentation
 for
usage while we are finalizing a tutorial specific to numpy/numpy.
Please submit all your feedback on the NumPy codespace in this tracking
issue: https://github.com/numpy/numpy/issues/23134.
I’d like to thank JP Ungaretti (@jungaretti), Sarah Kaiser (@crazy4pi314),
Sebastian Berg (@seberg), Melissa Mendonça (@melissawm), and Craig Peters
(@craiglpeters) for helping set it up and testing.

[Numpy-discussion] Numpy tools for getting the results of indexing operations

[Mark Harfouche]

I'm trying to make a few different file backed array-like objects.

However, I find myself struggling to get all the indexing operations right.

Is there a collection of utilities that answer questions like:

1. Given a shape, and key that would be valid in numpy, what is the
resulting shape.
2. Given a key, is it a fancy index key (I just don't want to support this
use case).
3. Given a key, can you "expand" the of the key so that it matches my input
shape?
4. Can you help me handle keys with `None` in them as an "np.newindex"?

I feel like dask, zarr, xarray would have all had to use functions like
these, I'm just wondering if there was any reconciliation of this kind of
functionality since the development of various `__array__` NEPs.

Best,

Mark
