Where do I put my environment variables for API credentials?
<p>I'm trying to work with the Spotify API and it needs client credentials. I've integrated spotipy and it works fine when I don't need to request user info (i.e. just downloading track names from an artist) but I wish to access audio features. </p>

<p>In what file/script and how do I include credentials? </p>

<p>This is what they say in the oauth2.py file:</p>

<pre><code>    You can either provid a client_id and client_secret to the
    constructor or set SPOTIPY_CLIENT_ID and SPOTIPY_CLIENT_SECRET
    environment variables
</code></pre>
