Heroku/python failed to detect set buildpack : <p>I'm a Django newbie, I created an app and want to deploy it using Heroku. However, when I do <code>git push heroku master</code> (I follow Heroku's getting started), this is what I got:</p>

<pre><code>Counting objects: 36, done.

<p>My root directory:</p>

<pre><code>├── assignment
