title: Setting environment variables in Google Colab
body: <p>I'm trying to use the Kaggle CLI API, and in order to do that, instead of using <code>kaggle.json</code> for authentication, I'm using <a href="https://github.com/Kaggle/kaggle-api#api-credentials" rel="noreferrer">environment variables to set the credentials</a>.</p>
  
  <pre><code>!pip install --upgrade kaggle
  
  !export KAGGLE_USERNAME=abcdefgh
  !export KAGGLE_KEY=abcdefgh
  
  !export -p
  </code></pre>
  
  <p>However, the printed list of env. variables doesn't contain the ones I set above.</p>
