title: Does Python classes support events like other languages?
body: <p>I'm working on my first Python project, and I'm already missing events in my classes. Perhaps it's not even called events in Python, but I would like to create "groups" in my classes to which function references can be added. At some point in my class all function references in my group would execute.</p>
  
  <p>Is this built into Python? (I'm using 2.7 at the moment)</p>
