What is Whistle?

Whistle is an Event Dispatcher library for the Python 3.5+ language.

It's largely inspired from Symfony's EventDispatcher component.

Using an event dispatcher is a great way to write loosely coupled extensible code, having each part only communicate using light events.

Add a listener to react to events

dispatcher.add_listener('spectacle.starts', on_spectacle_starts)

Dispatch it!

dispatcher.dispatch('spectacle.starts')
