title: Spotipy - set CLIENT_ID and CLIENT_SECRET
body: <p>Where do I go to set CLIENT_ID and CLIENT_SECRET so it's not stored in my python script?  The Spotipy documentation says the following, but I can't figure out where I need to go to input these environment variables.  Where do I set os.getenv?</p>
  
  <pre><code>    if not client_id:
          client_id = os.getenv('SPOTIPY_CLIENT_ID')
  
      if not client_secret:
          client_secret = os.getenv('SPOTIPY_CLIENT_SECRET')
  
      if not client_id:
          raise SpotifyOauthError('No client id')
  
      if not client_secret:
          raise SpotifyOauthError('No client secret')
  </code></pre>
