│   a.py

I'm triying to make a relative import from test_smallcircle.py to a.py as shown bellow

import sys
import os
sys.path.append(os.path.dirname("C:\\Users\\Manuel\\Desktop\\solution\\a.py"))
from a import smallest_circle # JUST HERE
from pytest_bdd import (
    given,
    scenario,
    then,
    when,
)
import pytest_bdd
from functools import partial

but it shows the next error

Unable to import 'a'

Answer 1

If you want a relative import, you need to go up a level:

from ..a import smallest_circle

Answer 2

I found the error, it was at the absulte path C:\\Users\\Manuel\\Desktop\\solution\\a.py that I append to the sys.path variable, the absolute path should be to the directory, not to the target file, so the solution was replacing it for C:\\Users\\Manuel\\Desktop\\solution
