class NewList(DQ):
    def first_method():
        print("hello")

I’m following Dataquest Mission Object-Oriented Python testing the code on Jupyter installed on my PC
When using directly on dataquest platform i receive no error.

The DQ should be used only in the dataquest platform for answer checking purposes. In the mission it is explained:

Usually, we’d define a class without anything in the parentheses, like this:

class MyClass():
    pass

In the rest of this mission, when you define a class in the code exercise, you’ll need to put DQ inside the parentheses:

class MyClass(DQ):
    pass

This makes the class inherit some special logic that allows our answer-checking system to work and give you feedback. We’ll remind you each time we tell you to define a new class so you don’t forget!
