I'm running into an error when attempting to import a file in the parent directory.

Code from test/log_line.py:

#! /usr/bin/env python3
from ..lib_common import log_line

Error:

$ py -3 test/log_line.py
Traceback (most recent call last):
  File "test/log_line.py", line 2, in <module>
    from .. import lib_common
ImportError: attempted relative import with no known parent package

Directory Structure:

./
|   test/
|   |   log_line.py
|   lib_common.py
|   __init__.py

lib_common.py contains the log_line function. Added __init__.py at the suggestion of @Pavel.

Any idea why Python is giving me the error? Googling the traceback returned one somewhat-related result. No luck.

Create an empty file named `__init__.py` in `./` – Pavel Dec 10 '17 at 23:36
@Pavel Didn't solve it. – Jacob Birkett Dec 10 '17 at 23:38

Even with `__init__.py` in the root it won't work because you're making `test` as your entry point. It's a bad design anyway, why would you want to do such a thing? – zwer Dec 10 '17 at 23:38

@zwer Because I didn't know of another way. Enlighten me, what is the better way? – Jacob Birkett Dec 10 '17 at 23:39
Start importing from your parent dictionary and work down. – Xantium Dec 10 '17 at 23:40
@spikespaz - do not import from children back to their parents (in package structure) do it other way around, as expected by Python. – zwer Dec 10 '17 at 23:41
@Simon If `from .. import lib_common` is what you mean, that doesn't help either. – Jacob Birkett Dec 10 '17 at 23:41
No I meant put `log_line.py` in the parent and `lib_common.py` in a subfolder – Xantium Dec 10 '17 at 23:43
@Simon `lib_common.py` shouldn't be in the `test/` directory because it needs to be used by other files in the parent package. – Jacob Birkett Dec 10 '17 at 23:45
Damn you've really messed yourself up. https://stackoverflow.com/questions/19668729/python-import-from-parent-directory may be of some help. – Xantium Dec 10 '17 at 23:47
