python how to import from the son of the son of the parent

Question

I have this hierarchy:

myfile.py
Spider
----__init__.py
----spiders
----------------file.py

and the file.py contains class myClass

I used to do this inside the myfile.py

from Spider.spiders.file import myClass

now I changed my hierarchy, and I put myfile.py inside a folder named newFolder, so the new hierarchy is:

newFolder
------myfile.py
Spider
----__init__.py
----spiders
----------------file.py

and I changed the path as this:

from ... import Spider.spiders.file.myClass

but I got invalid syntax in the spiders.spiders

help please

The mention answer doesn't help me, please help me – Marco Dinatsoli Mar 19 '15 at 10:56 — Marco Dinatsoli, Mar 19 '15 at 10:56

In from <a> import <b> syntax you should specify module path before import: from <a>.<b> import <c>:

from ...Spider.spiders.file import myClass

You can also add parent directory to path:

import sys
sys.path.append("..")
from Spider.spiders.file import myClass

I got this error `ValueError: Attempted relative import in non-package` – Marco Dinatsoli Mar 19 '15 at 09:50
@MarcoDinatsoli, you should have `__init__.py` in the same folder with your `myfile.py ` (it can be empty) – Daniil Ryzhkov Mar 19 '15 at 09:52
I have `__init__.py` file inside the `newFolder` and i still got this error `ValueError: Attempted relative import in non-package` – Marco Dinatsoli Mar 19 '15 at 09:56
@MarcoDinatsoli how do you run the script? – Daniil Ryzhkov Mar 19 '15 at 10:11
as always, i run the cmd in that folder and call the script name – Marco Dinatsoli Mar 19 '15 at 10:14
If you want to use relative path you should run scripts with -m parameter. More info: http://stackoverflow.com/questions/72852/how-to-do-relative-imports-in-python – Daniil Ryzhkov Mar 19 '15 at 10:15
