Proper relative imports: “Unable to import module”

Question

I have a project structured like this:

.
└── myapp
    ├── app.py
    ├── models
    │   ├── hello.py
    │   └── world.py
    └── requirements.txt

Answer 1

Since hello.py and world.py are in the same folder (aka package), you should import the Hello class in world.py as follow:

from .hello import Hello

As described in this thread: What does a . in an import statement in Python mean?

The . is here to indicate the import from the current package.
