Relative import correction without sys or os
Question: I've read almost all of the solutions for fixing relative imports and none of
them seem to work. Here's my current structure:

    
    
    structures
    \ containers
      \ queue.py
    \ trees
      \ binaryTree.py
    

I want to import the queue in to my binary tree file but I'm getting slammed
with relative import issue. I tried `__init__.py` but that doesn't seem to
solve the relative import issue. Is there a solution to this? (I'm on Python
3.3.x)

Edit:

This is my import statement

    
    
    from .containers.queue import Queue
    

and the error:

    
    
    Traceback (most recent call last):
      File "binaryTree.py", line 1, in <module>
        from .containers.queue import Queue
    SystemError: Parent module '' not loaded, cannot perform relative import
    


Answer: 
     from ..containers.queue import Queue
