Handle import of modules inside of a project

Question

I have the following project architecture (simplified):

root/ main.py mypackage/ __init__.py module1.py module2.py ci_scripts/ script1.py script2.py doc/ doc

where the root is nothing more than a folder.

How do I import module1 and module2 in script1.py for example?

I tried to:

Add the relative path inside script1.py: from ..mypackage import module1
The absolute path
Use of sys package to append the path of mypackage

To give more context, I was expecting that the following code inside of script1.py would work:

from ..mypackage import module1 module1.func1()

but I get:

ImportError: attempted relative import with no known parent package

And when I try to use the absolute path:

import mypackage.module1 module1.func1()

I get the following error:

ModuleNotFoundError: No module named 'mypackage'

No, in theory I know how it should be done but in my example, importing with relative or absolute paths does not work — kurisukun

You should edit your question to reflect what you are asking then. Currently you are asking what is the most pythonic way to import, not how to troubleshoot failing imports. — oskros

I followed the recommandations from here but Adrian Mole's answer is in the same spirit and it did the trick! Thank you — kurisukun

Your absolute import probably does not work because your root folder is not set to be mypackage. You can see here on how to do that: python: Change the scripts working directory to the script's own directory

Alternatively, you can use relative imports. You are correctly importing with from ..mypackage import module1 - however, you cannot execute a script directly with a relative import. You need to import the script into some other module which you are then executing. See explanation here: Relative imports in Python 3
