[Numpy-discussion] searching a list of arrays

Hi,
I have a list of numeric-23.8 arrays:
a = [array([0,1]),
array([0,1]),
array([1,0]),
array([1,0])]
b = [array([0,1,0]),
array([0,1,0]),
array([1,0,0]),
array([1,0,0])]
and I want to make a new list out of b:
c = [array([0,1,2]),
array([1,0,2])]
where the last index in each array is the result of
b.count([0,1,0]) # or [1,0,0]
The problem is that the result of b.count(array([1,0,0])) is 4, not 2, and
b.remove(array([1,0,0])) indescriminantly removes arrays from the list.
a.count and a.remove work the way I expected.
Does anyone know why 1x2 arrays work, but 1x3 or larger arrays do not?
Thanks,
Darren
