title: Deleting a database file in :memory:
body: <h3>Background and Question</h3>
  
  <p>We are using <code>:memory:</code> to store our database when we are testing and would like to remove this before each test case run so that we will start from the beginning with an empty database for each test case. (If we were storing the database on the disk we would simply remove the file)</p>
  
  <h3>Our Setup</h3>
  
  <ul>
  <li>We are using Python's <code>unittest</code> module</li>
  <li>(Python version: 3.6)</li>
  <li>This is what our database creation looks like: <code>db_connection = sqlite3.connect(":memory:")</code></li>
  </ul>
  
  <hr>
  
  <p>How can we delete our database from memory?</p>
