Initialise class object by name
<p>Since everything in python is an object, i was wondering if there was a way i could initialise a class object using the name of the class</p>

<p>for example, </p>

<pre><code>class Foo:
    """Class Foo"""
</code></pre>

<p>How could i access this class by "Foo", ie something like <code>c = get_class("Foo")</code></p>
