I tried the following code but when I opened my env file it was still empty.
import os
from os.path import join, dirname
from dotenv import load_dotenv
dotenv_path = join(dirname(__file__), '.env')
load_dotenv(dotenv_path)
os.environ['ORI'] = '123'
You need dotenv.set_key
for that, like this:
import dotenv
dotenv_path = "my-custom-dotenv"
# dotenv.set_key will create a dotenv file
# with the specified path if non existing, then add the "ORI" variable
dotenv.set_key(dotenv_path, "ORI", "123")
# add the IRO variable
dotenv.set_key(dotenv_path, "IRO", "321")
# change the ORI variable
dotenv.set_key(dotenv_path, "ORI", "456")
# remove the IRO variable
dotenv.unset_key(dotenv_path, "IRO")
