Relative importing python module from a subfolder from a different subfolder

Question

I\'m trying to use alembic which is an sqlalchemy tool in python. You type a command and it generates a folder \"alembic\" with py files inside. The py file inside, needs to lin

Is myapp a self-contained application, or a sub-application such as ones that you can find using Django? If it's a self-contained app, then you're kinda going about things wrong. What you really want to do is to install the dependencies that your app has in order to be able to access them without having to use relative imports and the like (which is bad practice, especially if anyone but you is using the app).

What you likely will want to do (again, if it's self-contained):

• Set up a virtual environment for your app (I highly recommend the use of virtualenvwrapper, which I just wrote about in my shiny new (and incomplete) blog: http://demianbrecht.github.com/posts/2013/01/02/virtualenvwrapper/
• Install alembic as a dependency: pip install alembic
• Create a requirements.txt file: pip freeze > requirements.txt

Now, you should be able to use alembic via import alembic from anywhere within your project.

Edit:

Your directory structure is also a little wonky. You'll want to put all of your app-specific modules into another myapp subdirectory:

myapp
    myapp
        __init__.py
        configs/__init__.py

The reason for this is so that you can add myapp to your PYTHONPATH and be able to import any modules from your app via from myapp import foo. As it stands, if myapp is on your PYTHONPATH, you'll only be able to access the submodules from the second namespace level (i.e. import configs), which is bad for obvious reasons.
