     ^ This is a comment, you are not importing numpy!

I think it is generally better to not do

from ... import *

because it messes up the namespace; it can happen that a second module  
overwrites a function from the first module.
This happens for example with:

from numpy import *
from pylab import *

pylab has a "load" function which is not the same as the numpy "load"  
function.

I always use
import numpy as N
