Python's import statement really does two different things.

from MODULE import SYMBOL
from PACKAGE import MODULE

So far so good.  But if you have a package inside a package, as in
quixote/server/simple_server.py), you cannot do:

import PACKAGE
PACKAGE.PACKAGE    # No, the subpackage has not been imported.
           # PACKAGE contains only the variables defined in
           # PACKAGE/__init__.py .

What you want to do is:

import quixote
import quixote.server   # Or "from quixote import server".

This loads only the variables in quixote/server/__init__.py .  If you
want to refer to a module in the quixote/server package, you have to
import it separately.

import quixote.server.simple_server
or
from quixote.server import simple_server
or
from quixote.server.simple_server import run
