If "/python_mvc_calculator/calculator/controller" is a folder and if you 
have a file __init__.py into this folder, you have to use:

sys.path.insert(0, "/python_mvc_calculator/calculator/controller")
from calculatorcontroller import foo # or import calculatorcontroller

But the init file must be named __init__.py NOT init.py as sayed in 
askubuntu.
