Python 3.5.1 import class in the same directory

So I am having trouble importing classes in the same directory and getting them to work properly.

I currently have the following hiearchy

My problem is between the 2 files in the bbsource directory. I have figured out how to get access from the bbsource directory down to the classes in the objects directory and vice versa but when I try to from BouncyBallEnv import BouncyBallEnv in the Console class I get the following error:

File "E:\PycharmProjects\BouncyBallPythonV0\bbsource\Console.py", line 5, in 
    from BouncyBallENV import BouncyBallEnv
ImportError: cannot import name 'BouncyBallEnv'

I have tried several things like:

from bbsource import BouncyBallEnv

from bbsource.BouncyBallEnv import BouncyBallEnv

But I can't get it to work.

The only time I could get it to work is when I did the following:



    import bbsource.BouncyBallEnv
    #Extra
    print(bbsource.BouncyBallEnv.BouncyBallEnv.WIDTH)

But there must be a better way to do it than that so that I wouldn't have to type that lengthy statement that is in the print statement every time that I want to use a static variable in BouncyBallEnv.

I am still quite confused on how the Python importing works so I'm not sure how to go about doing this. Thank you.

NOTE: Running Python 3.5.1

It is abosolue_import rule.

try

from .BouncyBallENV import BouncyBallEnv

to access module in relative position.

besides, there should be an __init__.py file under bbsource directory

the thing you need is aliases :

import bbsource.BouncyBallEnv as bbe
#Extra
print(bbe.WIDTH)

and you can't import a module with the from ... import ... syntax. Only attributes. It work like this :

import <module> [as <alias>]

or

from <module> import <attribute> [, <attribute2>...]  # import some attributes
from <module> import *                                # import everything

with the second one, you could have done :

from bbsource.BouncyBallEnv import WIDTH
# the variable WIDTH is directly loaded : watch out for collision !

print(WIDTH)
