The relative import feature of Python3 is not compatible with Jupyter or REPL, how to fix it?
Assuming if I have 2 files:
in something.py:
def a():
<... do something>
in b.py:
from .something import *
a()
then b.py theoretically should work when being executed as a module, thanks to the relative import feature (How to do relative imports in Python?)
However, when b.py is being evaluated in REPL (using eval() function), or b.py is converted to a jupyter notebook. Running will simply triggers:
ModuleNotFoundError: No module named 'main.something'; 'main' is not a package
This is very annoying: it basically means jupyter & python file have to use 2 versions to do the same thing, is there a way for relative import that works in all 3 cases?

Not sure about the specifics of how your code is structured, but your question might possibly a duplicate of this: stackoverflow.com/questions/34478398/…; basically, hack your module path so that it includes the directory that contains your code, and then import your code like a module.

Agreed, but there are many different ways to hack a REPL/jupyter's module path, I'm simply looking for a concise and widely-accepted solution

What exactly do you mean byb.py is being evaluated in REPL? Oh, and that 'recently introduced' link? It's from 2008.

@hpaulj yeah you are right, I thought it was introduced in python 3, turns out that it's already there for a long time, just not popular

This problem has nothing to do with relative imports. You would have the exact same problem with absolute imports.
