What i want to is, I have foo.py it imports classes from bar1, bar2, and they both need bar3, e.g.
foo.py
from src import *
...
src/ __ init__.py
from bar1 import specialSandwichMaker
from bar2 import specialMuffinMaker
src/bar1.py
import bar3
class specialSandwichMaker(bar3.sandwichMaker)
...
src/bar2.py
import bar3
class specialMuffinMaker(bar3.muffinMaker)
...
is there a more efficient way to make bar3 available to the bar1 and bar2 files without having them directly import it?
