Natasha2012 [34]

Answer:

import random

class Arithmetics(object):

   trial = 2

   score = 0

   is_end = "Y"

   

   def start(self):

       while self. is_end == "Y":

           self. level1()

           self. level2()

           self. level3()

           self. is_end = input("Do you want to play again? Y/N: "). upper()

       quit()

   def level1(self):

       print("--------------------Level 1--------------------\n\n Addition:")

       for _ in iter(list, 0):

           num1 = random.randint(1,5)

           num2 = random.randint(1,5)

           if self. score == 5:

               print("Congrat! advance to next level\n")

               self. init_()

               break

           print(f"{num1} + {num2}")

           result = int(input("Your answer: "))

           if result == num1 + num2:

               self. increase_score()

           elif self. trial == 0:

               print("Sorry dear, you failed to pass the text.")

               self. end_game()

           else:

               self. trial_reduce()

   def level2(self):

       print("--------------------Level 2--------------------\n\n Addition again:")

       for _ in iter(list, 0):

           num1 = random. randint(1,9)

           num2 = random. randint(1,9)

           if self. score == 5:

               print("Congrat! advance to next level\n")

               self. init_()

               break

           print(f"{num1} + {num2}")

           result = int(input("Your answer: "))

           if result == num1 + num2:

               self. increase_score()

           elif self. trial == 0:

               print("Sorry dear, you failed to pass the text.")

               self. end_game()

           else:

               self. trial_reduce()

   def level3(self):

           print("--------------------Level 3--------------------\n\n Subtraction:")

           for _ in iter(list, 0):

               denum = random. randint(6,9)

               num = random. randint(1,5)

               if self. score == 5:

                   self. init_()

                   self. end_game()

                   break

               print(f"{denum} - {num}")

               result = int(input("Your answer: "))

               if result == denum - num:

                   self. increase_score()

               elif self. trial == 0:

                   print("Sorry dear, you failed to pass the text.")

                   self. end_game()

               else:

                   self. trial_reduce()

   #classmethod

   def trial_reduce(cls):

       cls. trial -= 1

   #classmethod

   def increase_score(cls):

       cls. score += 1

   #classmethod

   def init_(cls):

       cls. trial = 2

       cls. score = 0

   def end_game(self):

       print("Congrats kiddo! You are a math wiz.")

game = Arithmetics()

game. start()

Explanation:

The python class defines the arithmetics class with three-level mathematics for children defined as methods for the class. There are three class methods namely; 'trial_reduce', 'increase_score', and 'init_' with each of them decreasing the trial attribute, increasing the score attribute by one, and initializing the class attributes to its initial state.

The 'end_game' prints a message at the end of the program. Each level is in a loop and counts five times if the answers are correct.
