Cannot import my own dependencies in Python

Question

I have created utils.py and constant.py (saved in the same folder of all src file) and I wrote this in main.py

import utils
import constant

but when I try to run the entire program it gives me this error:

Unable to import 'utils'

and if I open utils.py I noticed this error:

Unable to import 'constant'

(because I need constant also in utils.py)

How can I solve it?

do you have an \_\_init\_\_.py file in your dir? – user2717954 Dec 08 '19 at 14:15 — user2717954, Dec 08 '19 at 14:15
are your files in the same directory? – Ahmad Moussa Dec 08 '19 at 14:23 — Ahmad Moussa, Dec 08 '19 at 14:23
@AhmadMoussa yes I put them in ./src folder – Elliot Alderson Dec 08 '19 at 14:28 — Elliot Alderson, Dec 08 '19 at 14:28

You can try this from . import utils and have a look at this Relative imports for the billionth time

try this one:

import sys

sys.path.append("<path/to/project>")

import utils

Or

from .utils import *

It give me this error: from . import utils ImportError: attempted relative import with no known parent package – Elliot Alderson Dec 08 '19 at 14:29
Same problem :/ – Elliot Alderson Dec 08 '19 at 14:44
Can you share tree structure of src folder? – python_user Dec 08 '19 at 14:47
and where is `main.py` where you are trying to import. – python_user Dec 08 '19 at 14:51
my `main.py` is `TikTokTool.py` – Elliot Alderson Dec 08 '19 at 14:53
try `from .utils import *` – python_user Dec 08 '19 at 14:54
it doesn't work, now is full of "Undefined variable" – Elliot Alderson Dec 08 '19 at 15:01
restart your IDE – Ahmad Moussa Dec 08 '19 at 15:07
done but same error: from .utils import * ImportError: attempted relative import with no known parent package – Elliot Alderson Dec 08 '19 at 15:10
Create a completely new folder and try to do the same with basic funtions (e.g just a function that prints something). Import that from another file in the directory. If that fails then the issue is in your setup. – Péter Leéh Dec 08 '19 at 15:15

The correct way of importing functions from another file is done like this:

from file_name import function_name

If you want to import everything you should do this:

from file_name import *
