For #7, now you have a performance problem of importing every time you run that function. Rather, you can place the import at the bottom of b.py and be okay.

Python caches modules imported, you can check it out in your local shell with: import sys ; sys.modules. That's why whenever you make changes to a module which has been already loaded you won't see the changes until you load the module again, either quitting the shell or using reload(module) on Python 2.x

The author states that Python is smart enough not to reimport a file that has already been imported. Is that not the case here?
