Yes, the key is what "names" are "imported" into the current namespace 
(what names are visible to your code).

import numpy

loads the module and places the name "numpy" in the current namespace 
which points to the loaded module. 

from numpy import *

loads the module and places all the "exported" names from numpy into the 
current namespace.  The list of exported names, however, does not 
include the module numpy itself and so the current namespace does not 
get a "numpy" entry.
