although there are many posts on the internet as well as some posts on stack overflow, I still want to ask about this nasty python "import" problem.
OK. so, the open source code organization is usually like this:
project/src/model.py;
project/test/testmodel.py
if I put the famous __init__.py in project directory and also in src/ and test/ subdirectories,
and then put "from project.src import model" for the testmodel.py.
it does not work! keep telling me that the Module named "project.src" is not found!
how can I solve the problem without changing the code structure?

You shoud not add the project directory to your pythonpath but it's parent, e.g. imagine the setup
/home/user/develop/project/src/model
You'd add /home/user/develop to PYTHONPATH
If that still doesn't work, make sure you don't have a 'project.py' insite project/src/model.

Make sure you have the parent directory of project/ on your pythonpath, rather than the project directory. If you add the project path itself, imports like import project.src will look for project/project/src.

The directory where project is located is probably not in your python path.

You can use a relative import (assuming Python 2.5+) from testmodel.py, like:
from ..src import model
However, this does not work if you're running testmodel.py as the main module.
