Just wanted to share a simple Python terminal quiz I made just as practice. If you have any suggestions or edits let me know! :saluting_face:

import os
# Clears the screen
def clear_screen(message=''):
    os.system('cls' if os.name == 'nt' else 'clear')
    if message != '':
        print(message)
#Welcome message and point variable
print('Welcome to the Halo Quiz!')
answers_correct = 0
points = answers_correct
#Main menu of the quiz
def main_menu():
  playing = input('Do you want to begin? (y/n) ').lower()
  while True:
    if playing == 'y':
      print('Lets begin!')
      question_one()
      break
    elif playing == 'n':
      print('Your loss!')
      break
    else:
      print('Invalid input, please type "y" or "n" ')
      main_menu()
#Questions are listed below
def question_one():
  clear_screen()
  global points
  print('What year did Halo: Combat Evolved release?')
  print("")
  print('a) 2003')
  print('b) 2001')
  print('c) 2000')
  print('d) 1999')
  answer = input('').lower()
  
  while True:
    if answer != 'b':
      print('Incorrect! Halo: CE was released in 2001')
      print('')
      input('Press Enter to continue...')
      question_two()
      break
    else:
      points += 1
      print(f'Correct! You earned 1 point! Your total points is now: {points}')
      print('')
      input('Press Enter to continue...')
      question_two()
      break      
def question_two():
  clear_screen()

  a) Steve Downes
  b) Chris Farley
  c) Keith David
  d) Seth McFarlan

  a) Sergeant

  print(f'For this attempt you earned a {total_points:.1f}%.')
  print('')
  input('Would you like to retake the quiz? (y/n) ').lower()
  #Retaking the quiz 0's out your points and returns to the main menu
  while True:
    if input != 'y':
      points = 0
      main_menu()
      break
    else:  
      print('You may now exit the program')
      input('Press Enter to Exit...')
