Look at the arrow, it is placed AFTER closing the parenthesis, and thus denotes what the run method returns: A List of Dictionaries (or, practically, a list of events that you use like here ).

( ref ) Helps type checkers: By hinting at what type you want the object to be the type checker can easily detect if, for instance, you’re passing an object with a type that isn’t expected. Helps with documentation: A third person viewing your code will know what is expected where, ergo, how to use it without getting them TypeErrors. Helps IDEs develop more accurate and robust tools: Development Environments will be better suited at suggesting appropriate methods when know what type your object is. You have probably experienced this with some IDE at some point, hitting the . and having methods/attributes pop up which aren’t defined for an object. Why is this needed? They are not needed, you can completely remove them and nothing will change:def run( self, dispatcher: CollectingDispatcher, tracker: Tracker, domain: Dict[Text, Any] ) -> List[Dict[Text, Any]]: is the same asdef run(self, dispatcher, tracker, domain):

Check out the Rasa Learning Center and Rasa YouTube Channel . Rasa Actions are regular Python, if you know Python, you know Actions. All the extra stuff is explained in the Action Server Docs . What are you struggling with specifically?
