Include multiple modules on PyDev project

Question

So, I want to input previously created classes in my current Python project.

For this purpose I created a folder called lib and I create one __init__.py file in it. My file structure looks like this

project_folder
    lib
        class1_folder
            class1.py
        class2_folder
            class2.py
     _init_.py
     project_script.py

In the __init__.py file located in the main project folder, I have 2 lines of code.

from class1_folder import class1
from class2_folder import class2

I want to be able to use the classes that I implemented in my project_script.py. How would I be able to call them if they are nested so deeply? In project_script, I do the following from lib.class1_folder.class1 import * But I get an ImportError: No module named class1_folder

Answer 1

You need to add the __init__.py file to each folder which should be treated as a package (for your example, they should be added to class1_folder and class2_folder).
