Python Imports From The Directory Above

问题:

I have a directory structure for my python application where in the main folder I have a folder called handlers and in that file I have a base.py that all handlers should inherit from . I also have a folder called users that contains all the handlers relating to users.

\main
      \handlers
      base.py
      __init__.py
      \users
                __init__.py
                authenticated.py
                logout.py   

My issue is I can't import the base in any file in the users folder but can import from the users folder. I know that I have to do something like bellow

from ..handlers import *    

But that does not work for some reason all I am trying to do is import base.py into files in the users directory and other directorys I add at a later date.

回答1:

import sys
sys.path.append('/your/dir/goes/here')
from base import foo

Something like that should permit you to import stuff from any directory of your choosing.

回答2:

To enable relative import, add main/__init__.py to make main directory into a Python package. The main's parent directory should be in sys.path.
