title: Insert Null into SQLite3 in Python
body: <p>I am trying to insert a <code>None</code> value into a row entry of my db. The table <code>present</code> exists</p>
  
  <pre><code>db.execute("INSERT INTO present VALUES('test', ?, 9)", "This is a test!")
  db.execute("INSERT INTO present VALUES('test2', ?, 10)", None)
  </code></pre>
  
  <p>but I get an error:</p>
  
  <pre><code>ValueError: parameters are of unsupported type
  </code></pre>
