title: Initialise class object by name
body: <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>
