Multilevel relative import

Question

Multilevel relative import

I have following folder structure

top\
   __init__.py
   util\
      __init__.py
      utiltest.py
   foo\
      __init__.py
      foo.py
      bar\
         __init__.py
         foobar.py

I want to access from foobar.py the module utiltest.py. I tried following relative import, but this doesn't work: from ...util.utiltest import *

I always get ValueError: Attempted relative import beyond toplevel package

How to do such a multileve relative import?

Answer 1

You must import foobar from the parent folder of top:

import top.foo.bar.foobar

This tells Python that top is the top level package. Relative imports are possible only inside a package.
