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,
A
array([0, 1, 2, 3, 4, 5, 6, 7, 8, 9])
A[0:5]
array([0, 1, 2, 3, 4])
A[5:]

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].
Ah, I see what you are asking now.
The answer is "no"; this is just the way that slicing works in Python in general. numpy merely follows suit. It is something that you will get used to with practice. My sense of "funkiness" and "reasonableness" is the opposite of yours, for instance.
