[Numpy-discussion] Getting an item in an array with its coordinates given by another array

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
take method would be what I wanted but it is not... The [] operator does not
work on array(but it seems to give the expected result with a tuple or a
list). Is there a method for this ?
