When I run this code I get the error:

File "c:\Users\santh\OneDrive\Documents\PyQt5\yeah - Copy.py", line 481, in frame=m.questions AttributeError: 'makequestions' object has no attribute 'questions'

Answer 1

Try to add/declare property questions in your class __init__ method, smth like:

class MakeQuestions(QMainWindow):
    def __init__(self):
        self.questions = None
        super(MakeQuestions, self).__init__()
        ...
