Python extend matrix
<p>I am writing a program in python, and i am storing most of my data is matrixes such as this:</p>

<pre><code>users = {
    'user1': {'name':'Jack Renshaw', 'password':'randompass'}
}
</code></pre>

<p>How can i add a row to this, like with a standard list</p>

<p>Edit:</p>

<p>I actually want to append the data within the matrix, creating a new set. I worded the question poorly. I want to have permanent data stored so i can retrieve it if the application is closed.</p>

<p>Thanks</p>
