Actions.py

This files contains your custom actions which can be used to run custom Python code.

See this guide on how to implement these action: Actions

This is a simple example for a custom action which utters “Hello World!”

You can also set the parameter return_sequence: True for the RegexFeatureizer also.

Did try that , not working !! Also is my actions.py written in right way ?
