Load environment variables in python

Question

Trying to load environment varibles in python module

import os
    
class Config(object):
    port = os.environ.get("PORT") or 5000
    
print(Config.port)
    
$ 5000

Answer 1

This is an easy fix for the problem I just experiences with flask

• Create virtual environment using pip or pipenv ie virtualenv env
• Activate the virtual environment source env/bin/acivate
• Install python-dotenv module pip install python-dotenv

On top of your python file have something like this

In my .env file I have a variable named MY_VARIABLE

MY_VARIABLE=Somevalue

In my app.py I have this

import os

from dotenv import load_dotenv
# Loading up the values
load_dotenv()
class Config(object):
    port = os.environ.get("MY_VARIABLE") or 5000

print(Config.port)

Output

$ Somevalue
