Python Database
<p>My question is how to create a simple database in python. My example is:</p>

<pre><code>User = {
'Name' : {'Firstname', 'Lastname'},
'Address' : {'Street','Zip','State'},
'CreditCard' : {'CCtype','CCnumber'},
}
</code></pre>

<p>Now I can update this User's information just fine, but how do I</p>

<ol>
<li>Add more users to this data structure. A dictionary of dictionaries?</li>
<li>Allow users to have more than one credit card, a many to one relationship</li>
</ol>

<p>Thanks for any responses, I've been trying to wrap my head around this for awhile</p>
