Create 3D array using Python

Question

I would like to create a 3D array in Python (2.7) to use like this:

distance[i][j][k]

And the sizes of the array should be the size of a vari

def three_d_array(value, *dim):
    """

    """

    return [[[value for _ in xrange(dim[2])] for _ in xrange(dim[1])] for _ in xrange(dim[0])]

if __name__ == "__main__":
    array = three_d_array(False, *(2, 3, 1))
    x = len(array)
    y = len(array[0])
    z = len(array[0][0])
    print x, y, z

    array[0][0][0] = True
    array[1][1][0] = True

    print array

Prefer to use numpy.ndarray for multi-dimensional arrays.
