Import file from parent directory?

Question

I have the following directory structure:

application
    tests
        main.py
    main.py

application/main.py contains some functions.

Answer 1

First of all you need to make your directories into packages, by adding __init__.py files:

application
    tests
        __init__.py
        main.py
    __init__.py
    main.py

Then you should make sure that the directory above application is on sys.path. There are many ways to do that, like making the application infto a package and installing it, or just executing things in the right folder etc.

Then your imports will work.
