Python ImportError loading module within subfolder

Question

I have the following structure

abc/ __init__.py settings.py tests/ __init__.py test.py

in test.py, I am getting an ImportError for

#test.py import abc.settings

You have to add the main directory (where abc is in), to your sys.path — Wolph

@BlackVegetable oh, so if I move tests folder to the same level as abc then it should work — yayu

My comment was slightly mistaken. Look to @Wolph for the correct answer. — BlackVegetable

If you feel like getting your hands dirty, you can try out this module: docs.python.org/2/library/imp.html — BlackVegetable

That seems like an odd arrangement for tests. See e.g. jeffknupp.com/blog/2013/08/16/… for a handy guide to structuring a package. — jonrsharpe

You have two ways.

Firstly, by setting the path variable

import os import sys sys.path.insert(0, <Complete path of abc>)

Or by using relative imports.

I cannot mess with sys.path as the framework already does this. could you talk about the relative import method? I tried from ..abc import settings and ran it with python -m but I'm still getting an error

The variable sys.path is a list of strings that determines the interpreter’s search path for modules. It is initialized to a default path taken from the environment variable PYTHONPATH, or from a built-in default if PYTHONPATH is not set. You can modify it using standard list operations:

you need to add your root directory to sys.path :

import sys sys.path.append('path_of_root')

Aldo '..'+sys.path[0] can give you the path of abc directory !
