Yes it does, after from scipy import array, but you only solved the 
problem of array, that is what if other names arouse ? I still don't 
understand what the problem is with doing import my_friends_module as 
MF, and use the functions as MF.foo. Using from module import *, that is 
importing everything from a module totally defeats the purpose of 
namespace (and is not specific to python; C++ namespace are exactly the 
same: doing from module import * everywhere is exactly the same than 
doing using namespace std, etc... everywhere in your header files, which 
is an horrible thing to do).
