Import functions from another directory

Question

I am running a python script (app.py) where I have to use two functions from another script (src.py), located inside another directory. The structure is the following:

Dir:
   Dir_1:
        __init__.py
        src.py
   Dir_2:
        app.py

I am using, in app.py, the following lines:

from pathlib import Path
PROJECT = Path(__file__).resolve().parent.parent
PROJECT = PROJECT/'Dir_1'

import sys
sys.path.insert(1, PROJECT)
from src import odd_all, even_all

to access to the functions odd_all, even_all declared inside src.py. However, I get the error: ModuleNotFoundError: No module named 'src'.

How could I solve this problem?

You can use the sys.path.append() to append the path of your file to the system's path:

import sys
sys.path.append('/.../Dir/Dir_1')

from src import odd_all, even_all

It still gives the same error message. – Ernesto Lopez Fune Feb 12 '22 at 23:05

Check the naming of src – Matei Piele Feb 13 '22 at 07:25

I managed to solve the problem. The issue was that PROJECT is a Posixpath object, while SYS accepts only strings. Therefore, the solution was just to transform PROJECT to string:

from pathlib import Path
PROJECT = Path(__file__).resolve().parent.parent
PROJECT = str(PROJECT)+'/Dir_1'

import sys
sys.path.insert(1, PROJECT)
from src import odd_all, even_all

Now everything works perfectly.
