如何在Django / Python中将一个模块导入另一个模块？

Question

I'm just getting started with Python and Django. So within my Django application, I created a new module and within that, I want to import some variable defined in the parent module. However, I am getting certain errors while I tried various combinations. Below is how my directory structure looks like

Now in my kafka_producer.py I am trying to import constants.py .

kafka_producer.py :

from confluent_kafka import Producer
import sys
import logging
import json
from my_app.constants import KAFKA_BROKER_URL

logging.basicConfig()

#Assign Configuration
conf = {'bootstrap.servers': KAFKA_BROKER_URL}
print(conf)

However, I am getting no module found error . What is the correct way of importing modules in Python?

Answer 1

It should work if you write:

from ..constants import KAFKA_BROKER_URL

Through this way, you leave the kafka directory and you are in your my_app directory.

Answer 2

Can you please paste full trace of error, as in : ModuleNotFoundError: No module named --name

I want to know what it is saying in --name.

One thing you can try is adding path of your app to the environment variable PATH.

Try adding below lines in your kafka_producer.py

import sys
import os
sys.path.append(os.path.dirname(os.path.dirname(os.path.abspath('__file__'))))
