Question

In problem set 5, I am stuck on question 2. Should I be implementing Trigger? It does not say to do that, but all that class is does is raise NotImplementedError if it is called.

Thanks.

Answer 1

from the instructions
"The class below implements the Trigger interface (you will not modify this)."

and
"We will define a number of classes that inherit from Trigger."

Answer 2

Thanks. But what is the point of this class if it doesn't do anything? What is there to inherit?

Answer 3

its type ... not sure what the advantage is - i suppose that later after you have implemented a lot of classes that inherit from Trigger if you think of an attribute that would be benificial to all of them then you could add it to the base class.
