I don't know if that's supposed to be a question or a statement. And no, I don't need anything, this is not my question. You on the other hand, want to allow people to help you easily. They can't copy-paste and run your code if it's in an image... — Tomerikoo

@Tomerikoo, Sorry sir In future question I will keep in mind. Actually I wanted to show all details like file structure, error log. — Manish Pushpam

No problem, that's good and important. It's just better to put it in the question in a more readable way. I'm sure you'll agree with me that it's hard to see anything from these pictures. Good luck — Tomerikoo

You import it as if you were to import any other Python module. In other words don't do this:

from .name import *

but do this:

from name import show_name

For example:

The contents of name.py:

def my_name():
    print("Your name goes here.")

Don't forget to Deploy your function after making changes.

Why some editors induce us to make this mistake? It should be a standard feature in pylint, for example!

An alternative approach that I find works well if your lambda function is a module is to save it as a module. So something like:

my_awesome_service
|--lambda_function.py
|--name.py
included_module_1
included_module_2

And then invoke using:

my_awesome_service.lambda_function.lambda_handler

Then the relative imports work and you don't need any changes to your code

This is a great approach, the unit tests in SAM CLI examples also work with this setup.
