ModuleNotFoundError -> Imported module cannot import another module

Question

Working directory is shaped like:

* main_script.py / module_to_import * __init__.py * script_1.py * script_2.py

In main_script.py we have

from module_to_import import script_1 script_1.call_something()

In script_1.py we have

import script_2 def call_something(): something = script_2.get_something() something = something + 1 return something

When main_script.py is run This returns a

ModuleNotFoundError: No Module named 'script_2'

I understand this could be provisionally resolved by directly importing script_2 into main_script.

Is there a way to resolve this so that script_1 can reliably import script_2 even when main_script has not imported script_2 itself?

When your package is structured as a subpackage, in script_1.py you can use either absolute import

import module_to_import.script_2 as script_2

or relative one:

from . import script_2
