In Python 2, I was able to create a file named .env within a project folder like so:
# .env
MY_ID=abc123
TOKEN=4567890
Then in a Python file in the same directory, I could read these variables like so:
# example.py
import os
id = os.environ["MY_ID"]
token = os.environ["TOKEN"]
This would work fine and load these variables from the file automatically when run.
In Python 3, this is not working (I get a KeyError when trying to read the first environment variable),
So instead I tried to use the python-dotenv package to load the variables like so:
# example.py
import os
from dotenv import load_dotenv
load_dotenv()
id = os.environ[“MY_ID”]
token = os.environ[“TOKEN”]
But this still results in a KeyError.
Trying os.getenv() instead of os.environ() (as I saw in forum postings) results in TypeError: 'function' object is not subscriptable.
Is there a simple way to read these variables as environment variables from a .env file using this paradigm or do I need to implement a custom config in Python 3?
