Please help In Python when i test it it gives me a error for all

Implement a word trigger abstract class, WordTrigger. It should take in a string word as an argument to the classs constructor.

WordTrigger should be a subclass of Trigger. It has one new method, is_word_in. is_word_in takes in one string argument text. It returns True if the whole word word is present in text, False otherwise, as described in the above examples. This method should not be case sensitive. Implement this method.

Because this is an abstract class, we will not be directly instantiating any WordTriggers. WordTrigger should inherit its evaluate method from Trigger. We do this because now we can create subclasses of WordTrigger that use its is_word_in function. In this way, it is much like the Trigger interface, except now actual code from the class is used.

# Whole Word Triggers # Problems 2-5 # TODO: WordTrigger # TODO: TitleTrigger # TODO: SubjectTrigger # TODO: Summa ryTrigger
