Import module on Python

Question

I'm currently trying to import a module on Python but I'm receiving the following message:

Traceback (most recent call last):
 File "test_db_conn.py", line 8, in <module>
 from config import config_reader
ModuleNotFoundError: No module named 'config'

Here's the folder structure:

config
 - __init.py
 - config_reader.py
 - config.ini 
db_functions
 - test_db_conn.py

And the code on 'test_db_conn.py':

# Import modules
from config import config_reader
import pymongo
# Query database and print result
db_client = pymongo.MongoClient(db_url)
db_status = db_client.test
print(db_status)

Are you able to help me with this?

Thank you in advance

• drum: your test file is already inside of config folder so you only need import config_reader
• rmso27: Sorry, that "folder structure" is wrong. I mistyped while creating the post. The test script is inside "db_functions" that is on the same level as the "config" folder.

You need to append the parent path of your project to the Python module search directory. I replicated your folder structure locally on my dev system, and was able to access a function named config_reader in the config_read.py module, within the config package.

import sys
import pathlib
parent_dir = pathlib.Path(__file__).parent.parent
sys.path.append(parent_dir.__str__())
from config.config_reader import config_reader
config_reader()

• rmso27: Thank you for your reply! I'll test it as soon as I get to my computer. I'll update you than.
• rmso27: Thank you for the tip! It didn't work with that exact same code but you point me in the right direction to fix the issue! Thank you!
