Can't import my own modules in Python

In your particular case it looks like you're trying to import SomeObject from the myapp.py and TestCase.py scripts. From myapp.py, do

import SomeObject

since it is in the same folder. For TestCase.py, do

from ..myapp import SomeObject

However, this will work only if you are importing TestCase from the package. If you want to directly run python TestCase.py, you would have to mess with your path. This can be done within Python:

import sys
sys.path.append("..")
from myapp import SomeObject

though that is generally not recommended.

In general, if you want other people to use your Python package, you should use distutils to create a setup script. That way, anyone can install your package easily using a command like python setup.py install and it will be available everywhere on their machine. If you're serious about the package, you could even add it to the Python Package Index, PyPI.

The function import looks for files into your PYTHONPATH env. variable and your local directory. So you can either put all your files in the same directory, or export the path typing into a terminal::

export PYTHONPATH="$PYTHONPATH:/path_to_myapp/myapp/myapp/"

You can try

from myapp.myapp import SomeObject

because your project name is the same as the myapp.py which makes it search the project document first

exporting path is a good way. Another way is to add a .pth to your site-packages location. On my mac my python keeps site-packages in /Library/Python shown below

/Library/Python/2.7/site-packages

I created a file called awesome.pth at /Library/Python/2.7/site-packages/awesome.pth and in the file put the following path that references my awesome modules

/opt/awesome/custom_python_modules
