Creating Python package fails because one file can't see the other

Question

I have 3 files in a Python module called flags.

lookup.py contains the line from data import list_of_data_items

If I then try to run

from flags import lookup

I get

ModuleNotFoundError: No module named 'data'

Importing data works without issue

>>> from flags import data
>>>

Tried both with no success. For the record I've tried importing with `import lookup` and `from lookup import *` no luck with either — Jonathan, Dec 19 '17 at 16:44
found solution, in `lookup.py` change to the line `from .data import list_of_data_items` or `from flags.data import list_of_data_items` — Stack, Dec 19 '17 at 16:48
That works very well. Thanks! If you put that in an answer I'll accept it. — Jonathan, Dec 19 '17 at 16:49
Would also appreciate whatever reference you find most useful to learn more about creating Python modules. — Jonathan, Dec 19 '17 at 16:50
I think answer is not required, you can read about relative imports here `https://stackoverflow.com/questions/14132789/relative-imports-for-the-billionth-time` — Stack, Dec 19 '17 at 16:51
