[Numpy-discussion] Function returns nothing!

[allan oware]

Hi All!

def height_diffs():
    h = []
    i = 0
    while True:
        x = raw_input("Enter height difference ")
        if x == 'q':
            break
        else:
            h.append(x)
            i = i + 1

    m = asarray(h,dtype=float)

    return m


why does return statement return nothing?
