Set toplevel for Python package -

i have folder structure:

okay, have below code in main application (main.py)

from modules.core import core1 print core1.housenumber() 

and below code in core1.py:

from ..engine import engine1 def housenumber():     house = engine1.badluck()     return house  

also code in engine1.py:

def badluck():     return 13 

this work without problem, alright.
now, here interesting part, have below code in widget1.py

def door():     return 'black' 

and code in core2.py:

from ...widgets import widget1 def doorcolor():     door = widget1.door()     return door 

and if change main.py to:

from modules.core import core1, core2 print core1.housenumber() print core2.doorcolor() 

i error: attempted relative import beyond toplevel package.

okay, if take main.py out of projectx in drive d , change main.py codes this:

from projectx.modules.core import core1, core2 print core1.housenumber() print core2.doorcolor() 

it work perfectly.
okay, understand if from modules.core import core1, core2 means modules top-level not projectxeven included __init__.pyto folder structure.

here question:

is there way can define toplevel folder in main.py without moving main file around?

note1: there solution adding full path like: from projectx.modules.core import core1 , from projectx.widgets import widget1, it's not best solution,cause have sys.path.append() , think there smart way.

note1: have done adding __all__ inside __init__.py of projectx:

__all__ = ['modules','widgets'] import modules import widgets 

i didn't result.
include above example here download/study.

you don't need relative import in corex.py files.

simply change core2.py:

-from ...widgets import widget1 +from widgets import widget1 

note: can refactor imports remove relative import.
