Python importing issue I'm having

my dir structure is like this

main/src/domain/entities.py
-entities.py has some classes
main/tests/test.py

in test.pt I have from domain.entities import MyCLass

both tests and domain dir's have __init__.py's.

It does not find the module i want though. I run the test.py with python3 test.py

Any ideas why?

It's far easier to utilize sys.path, but if you want a solution that doesn't involve messing with the globals, then here it is.

  1. Include an __init__.py file in the same folder as the module you want to import.
  2. Import the specific module you want from the file you want using the following syntax: from path.to.file.filename import MyClass

I tested this particular method moments ago. My folder hierarchy was one with a main.py, and two nested folders domains/entities. Each folder except for the uppermost level (i.e. the level that main.py lives in) has an __init__.py file in them.

Illustrated:

  • main.py
  • project/
    • __init__.py
    • domains/
      • __init__.py
      • entities/
        • __init__.py
        • module1.py

You need __ini__.py in every directory within the package

main/__init__.py
main/src/__init__.py
main/src/domain/__init__.py
main/src/domain/entities.py
main/tests/__init__.py

is main/src in sys.path? Python resolves module names by searching the directories in sys.path. For example "import ../module.py" is not valid. To fix your problem do something like this: In your "main/tests/test.py" file add:

import sys, os

sys.path.insert(0, os.path.abspath("../src") )

# Then try 
from domain.entries import MyClass

You will also need to make sure that main/src/domain contains an init.py file. Also you don't need init.py in main/tests unless your going to add it's parent directory to your path and import tests.something.

Hope this helps.
