 Doug Fresh · December 7, 2014 Iteration is the repetition of a similar step in programming. By recognizing patterns in programs, we can effectively reduce 90 lines of code, down to 26. This makes the code legible and makes it easier to maintain. Mel Addison · December 7, 2014 what is iteration? Steven the awesome · September 11, 2014 Thanks! Gary Murphy · September 11, 2014 If you are using those exact questions you could use iteration. ``class Quiz:    point = 0    def easy_questions(self):        while True:            try:                for question in range(10, 0, -1):                    vraag = int(input("What is 10 x " + str(question) + " = "))                    antwoorden = 10 * question                    if vraag != antwoorden:                        print("The answer is wrong! the correct answer is " + str(antwoorden))                    else:                        print("The answer is correct it was indeed " + str(antwoorden))                        self.point += 1                        print("Your note until now is: " + str(self.point))                break            except ValueError:                print("Make sure to enter valid number")            except ZeroDivisionError:                print("Don't divide zero")# ask for the classquiz = Quiz()#ask for the methodquiz.easy_questions()``
