Issue

Here is the directory and file as a tree:

.
├── my_dir
│   ├── a.py
│   └── b.py
└── outside.py

a.py has only one function:

def my_func_a():
    return "This is a test from a"

In b.py I have imported the a.py module and used its function inside another function:

from a import my_func_a
    
def my_func_b():
    print(my_func_a())
    return "This is a test from b"

Now, in outside.py, when I am running the code, I am facing the ModuleNotFoundError:

from my_dir import b

print(b.my_func_b())

the Error:

from a import my_func_a
ModuleNotFoundError: No module named 'a'

Solution

The importing should be as follows and it is working perfectly!

from .a import my_func_a
