Question

Basically I have written two modules for my Python Program. I need one module to import the other module.

Here is a sample of my file structure.

test_app 
    main.py
    module_1
        __init__.py
        main.py

    module_2
        __init__.py
        main.py

Main.py is able to import either of the two modules, but I need module_1 to import module_2, is that possible?

Answer 1

Yes. If your PYTHONPATH environment variable is set to test_app, you should be able to import module1 from module2 and vice versa.

I assume that you run your program like this:

python test_app/main.py

and that the program imports module1.main, which in turn imports module2.main. In that case there is no need to alter the value of PYTHONPATH, since Python has already added the test_app directory to it. See the Module Search Path section in the Python docs.
