title: How to set environment variables in VSCode when running Flask app?
body: <p>I have a Python Flask app and have lots of environment variables that I need to set when running my app. I normally run my app like so...</p>
  
  <pre><code>python3 -m app.py
  </code></pre>
  
  <p>I would like it so that I can set all the environment variables my app needs so that I do not need to export each time I reopen my terminal. It would be nice if it could be workspace-specific or project-specific. </p>
  
  <p>I know other editors like Pycharm can do similar things and was wondering how to do this in VS Code? </p>
