Cannot import functions in from one directory's subfolder to other pyhton files in same parent directories sub folders. How do I use init.py files

Question

parent_folder / subfolder1 / subsubfolder1/ a.py b.py subsubfolder2/ c.py d.py e.py subfolder2 / subsubfolder2/ f.py g.py subfolder3 / h.py i.py g.py

I want to import the functions from files h,i,g to all the subsubfolders py files. Can any one help me how do I do that. I have tried using sys.path.insert(0 , 'path') from h import funct1 , from g import funct1. It works II get this error ImportError: attempted relative import with no known parent package when I do from .h import funct1 and I also want to Implement this in docker files. Is there any other way? Thanks in advance !!

Answer 1

For your case it is best to use sys:-
for example to import in a.py use:

import sys
sys.path.insert(0,'../../subfolder3')
import h,i,g

Here we can use relative path in sys, '..' indicates moving one folder back

For Docker it is best to use relative path as:

import sys,os
sys.path.append(os.path.join(sys.path[0],'../../subfolder3'))
import h,i,g

This would work for docker. Please try and let me know if it works.
