Python has a mechanism both for getting an item and for setting an item.
The latter will end up doing this (python already does this for us):
x[:,d,:,d] = x[:,d,:,d] + 1
so there is an item assignment going on (__setitem__ not __getitem__)

If I run the following code:

x=np.arange(36).reshape(3,2,3,2)
y=x[:,d,:,d]
y+=1
In [85]: bi = (f.bolo_indices[np.newaxis,:]+
ones([7751,1])).astype('int')
In [86]: whc = (whscan[:,np.newaxis] + ones([1,107])).astype('int')
In [87]: array2d[whc,bi] = temp2d
I thought this had worked, but the values didn't seem to be going to the
right places when I re-examined them.

This works, but it feels wrong to me: I think there should be a way to
Hi numpy group,
I have a problem I know there is an elegant solution to, but I can't
wrap my head around the right way to do the indexing.
The problem:
I have a 2D array that has been chopped up into 3 dimensions - it was [ time
X detectors ], it is now [ scans X time X detectors ]. During
