event driven programming in python

When a registered event is received an event loop polls for new events and calls the matching event handlers. Applications can be developed to have an event-driven architecture which means its behavior revolves around event detection event forwarding and event handling.

Event source is an object that generates an event. Anything that happens in a user interface is an eventWe say that an event is fired whenever the user does something for example clicks on a button or types a keyboard shortcut. The main component of any asyncio based Python program has to be the underlying event loop.

Event handling has three main components Events. A source generates an Event and send it to one or. Similarly programmers can implement an event sourcing coding practice that models systems as a series of events and business objects.
