This method creates the index array for you. You only have to specify
the coordinates in each dimesion.

c[(2,3)] is the same as c[2,3] and obviously works as you expected.
Well, this is not indicated in the documentation.
This is true
In this case the constructor
tuple(arr)
should work just fine.
Sorry, I didn't know it could work (shame on me I should have tested).

Hi,
I'm trying to get an item in an array when I only have another array giving
the position.
For instance:
c = numpy.arange(0., 3*4*5).reshape((3,4,5))
c***(numpy.array((2,3), dtype=int))
[55, 56, 57, 58, 59]
I'm trying to figure what to put between c and ((2,3)). I supposed that the

c[[2,3]] is refered to as 'advanced indexing' in the numpy book.
It will
