create module function alias by import or assignment

Say I have import a module by using

import m

and now I want an alias to its function, I can use

from m import f as n

or 

n = m.f

I think there is no difference, is one preferred than another?

Use the first one if you only will need to get f. Use the second one if you need to import other things than f (m is still there). Other than that, they are the same.

There is no difference, as far as using the object n is concerned.

There is a slight logical difference: the first way will leave a name m bound in scope, and the second way will not. Though, the m module would still get loaded into sys.modules with either approach.

Using the import statement for this is more commonly seen.
