Is there a clean way to include the last element when subindexing numpy arrays?
Since the default behaviour of numpy arrays is to omit the “stop index”.
So for,

No that returns the subarray starting from index 5 to the end.

What I want to be able to return

array([0, 1, 2, 3, 4, 5])

(i.e. last element 5 included)

but without the funky A[0:6] syntax, which looks like it should return

array([0, 1, 2, 3, 4, 5, 6])

but since bumpy arrays omit the last index, returns

array([0, 1, 2, 3, 4, 5])

which syntactically would be more reasonable to be A[0:5].
