not able to import a file from an app to another

I have a django project with srtucture like this:

main_project

----main_project

<------libs

<<---------exceptions.py

----project_a

----project_b

In the views.py of project_a I am trying to import a folder named libs of main_project and a file from libs called exceptions.py, but I am getting the error
ImportError: No module named libs.exceptions

My code is :

from main_project.libs.exceptions import (
    APIException400,
    APIException405,
    APIException403,
    exception_handler_dispatcher,
)

Can someone tell me what am I missing here? With reference to https://stackoverflow.com/a/31407131/5080347 answer I even tried :

from main_project.main_project.libs.exceptions import (
        APIException400,
        APIException405,
        APIException403,
        exception_handler_dispatcher,
    )

but doesn't work.

It seems like you forgot to add __init__.py to libs directory.

The __init__.py is used to initialize Python packages. Check the documentation to better understand how things are working.

Your structure should looks as follow:

    project/
    |   
    |-- __init__.py
    |   
    |-- module_a/
    |   |-- __init__.py
    |   |
    |   |-- file1.py
    |   |
    |   |-- file2.py
    |
    |-- module_b/
    |   |
    |   |-- __init__.py
    |   |
    |   |-- file1.py
    |   |
    |   |-- submodule/
    |   |   |--__init__.py
    |   |   |
    |   |   |-- file1.py

When you import using from main_project.libs.exceptions, python expects that main_project is the package and libs and exceptions are submodules. So there must be a file named __init__.py in those directories. The init.py files are required to make Python treat the directories as containing packages. For further reading please refer to here.
