How to import a module in another module from the same subpackage?

Question

My package tree is as follows:-

My_package
    |
    +--__init__.py    (empty)
    +--mainfile.py
    +--main_modules
        |
        +--__init__.py    (empty)
        +--module1.py
        +--module2.py

The content of module2:-

class Wish:
    def greatings(self):
        print("Hello World!")

wish = Wish()

When I try to import wish from module2 in module1 as:- Content of module1:-

from module2 import wish

There is no error.

But when I import both modules in mainfile.py, Content of mainfile.py:-

from main_modules import module1
from main_modules import module2

An error occurs:-

Traceback (most recent call last):
  File "c:\Users\amuly\AppData\Local\Programs\Python\PyProgs\Test package\main package\mainfile.py", line 1, in <module>
    from main_modules import module1
  File "c:\Users\amuly\AppData\Local\Programs\Python\PyProgs\Test package\main package\main_modules\module1.py", line 1, in <module>       
    from module2 import wish
ModuleNotFoundError: No module named 'module2'

This is the screenshot of the issue:- Screen Shot

I have searched various related questions and tried all to my best but it is not working

Since module1 and module2 are on the same package level, you can simply do this in module1.py:

from module2 import wish

To import module2.wish from mainfile.py, you can do this:

from main_modules.module2 import wish

EDIT - in module1.py, change the import statement to this:

from main_modules.m2 import wish

using main_modules.m2 will help because the function calls are happening from mainfile.py. Hence, import statements in the subsequently called files will look at the imports relative to mainfile.py. I hope that makes sense.

@A.Paritosh - try [this](https://stackoverflow.com/questions/16981921/relative-imports-in-python-3) – Sindhu Satish Mar 30 '21 at 07:23
That works but a new problem arose. I have edited my question. – A.Paritosh Mar 30 '21 at 09:04

You have to remove the . in from .module2 import wish because they're on the same package level (as @Sindhu Satish already pointed out).

In you module1.py file, you have to change your import statement into this: from module2 import wish for it to work.

I hope I could help you!

I have added ss of my issue. For some reason it is not working. I must be doing some mistake but I can't put my finger on it. – A.Paritosh Mar 30 '21 at 08:07
New problem arose. When both modules imported in mainfile, module2 can not be imported in module1 – A.Paritosh Mar 30 '21 at 09:06
