Imports

The file containing the main() function that starts the application should reside at the project's top-level folder so you can use "absolute" imports.

Example

project
├── main.py
├── package1
│   ├── module1.py
│   └── module2.py
└── package2
    ├── __init__.py
    ├── module3.py
    ├── module4.py
    └── subpackage1
        └── module5.py

Consider the above folder structure. If you start the app by running python main.py you can use the following "absolute" imports from any file.

from package1 import module1
from package1.module2 import function1
from package2.subpackage1.module5 import function2
