Hey all,
With the recent merging of numpy/numpy#16759 <https://github.com/numpy/numpy/pull/16759> we’re at the point where ` ndarray` can be made generic w.r.t. its dtype and shape.
An open question which yet remains is to order in which these two parameters should appear (numpy/numpy#16547 <https://github.com/numpy/numpy/issues/16547>):
· `ndarray[Dtype, Shape]`
· `ndarray[Shape, Dtype]`
Hi Bas, Thanks for driving this forward! Just to speak for myself, I don't think the precise choice matters very much. There are arguments for consistency both ways. In the end Dtype and Shape are different enough that I doubt it will be a point of confusion. Also, I would guess many users will define their own type aliases, so can write something more succinct like Float64[shape] rather than ndarray[float64, shape]. We might even consider including some of these in numpy.typing. Cheers, Stephan
There has been a some discussion about this question in issue 16547, but a consensus has not yet to be reached.
Most people seem to slightly preferring one option over the other.
Are there any further thoughts on this subject?
