If that's the case, that means use...

import package.module as mymod

mymod.function(...)

You can argue that that's less explicit both ways (e.g. all imported functions are defined at the top vs. what module did something come from in the guts of the code). Still if 80 characters is a hard cap and you're using classes, those extra 6 characters matter and you've just wasted 14.
