Unresolved attribute reference '__' for class '__'

Question

I'm going through a beginner course and when I reached here the instructor made a separate file for the class and then imported it. I just added the class at the top because I've seen it work before. it doesn't work like this though but importing it from another file works. What am I doing wrong?

Full error message when running the program:

File "C:/Users/user/PycharmProjects/pythonProject1/app.py", line 54, in RunTest
    ans = input(Class.question)
AttributeError: type object 'Class' has no attribute 'question'

print("Your Score: " + str(RunTest(questionArray)) + "!") #added this part to check if I absolutely need to call the RunTest from outside

Answer 1

this is because you need to first create an instance of that class,

Example:

>>> class MyClass:
...    def __init__(self,question,answer) -> None:
...        self.question = question
...        self.answer = answer

you need to first instanciate the class into an object:

>>> myobject = MyClass(question="how good is potato",answer="delicious")

then you can call the self.question:

>>> myobject.question
"how good is potato"
>>> myobject.answer
"delicious"

Answer 2

You're passing a list of Class objects into the RunTest function.

When you iterate over this list, refer to the current object's .question and .answer attributes.

def RunTest(questions):
    score = 0
    for question in questions:
        ans = input(question.question)
        if ans == question.answer:
