Package Imports in Python
I am pretty new to Python, but I encountered this problem when someone tried recommending me to use packages. My directory (not actual names but just for example's sake) are as follows:
Main_Folder
- First_folder
__init__.py
first_file.py
- Second_folder
__init__.py
second_file.py
__init__.py
third_file.py
I want to use some functions I created on first_file inside second_file so I wrote both (on different times, not same):
from .first_folder import first_file
from Main_Folder.first_folder import first_file
And I get errors like:
<from first import>
ModuleNotFoundError: No module named '__main__.first_file'; '__main__' is not a package
<from second import>
ModuleNotFoundError: No module named 'Main_Folder'
However, when I do an import for third_file to any of the files inside using, it WORKS:
from First_folder.first_file import some_function
So I was just wondering if i was doing something wrong.
I know there are lots of questions like this existing and I already looked but i cannot get anything to work.. And I am new to Python too...
Update:
I ran both codes using their full absolute path
python python-import

What exactly were you running and from which directory? Which version of Python are you using? PEP 328 gives you a hint about the problem, it seems that__main__is set as the top level module (see also this question). However I don't see how you get this with..relative import since you should getValueError: attempted relative import beyond top-level packageinstead.

If you are sitting inMain_Folderthough and usingfrom .first_folder import first_file(note the single.) inthird_file.pyand runningpython third_file.pythen this perfectly explains the reported errors (as documented by PEP 328).

Thanks for the answers, I was running second_file.py. And also, you are right, it's only a single dot (.) and I get that error from using two dots.

Also I ran my code on both Main_Folder and also at Second_Folder but still getting the same error..

One way to make this work is to add the parent path to the python path as follows:
import sys
sys.path
sys.path.append('..')
then you should be able to import normally
