I have a python code and I'm getting Process finish with exit code 0. Problem is I'm not being asked to input any information, unlike what is supposed to be doing. its supposed to ask me to enter 6 numbers and get the average. why isn't it asking me for input>

def main(): total=0 for i in range(0,6): while (True): grade = int(input('Enter grade: ')) if(isInvalidScore(grade)): print('Enter valid grade') continue  else: break  total += grade avg = calc_average(total) print('Average grade is: ', avg) def calc_average(total): return total / 6 def isInvalidScore(score): status = True  if score < 0 or score > 100: status = True  else: status = False  return status #2nd part:  def main(): num=int(input('How many grades do you have')) total=0 for i in range(0,num): while (True): grade = int(input('Enter grade: ')) if(isInvalidScore(grade)): print('Enter valid grade') continue  else: break  total += grade avg = calc_average(total,num) print('Average grade is: ', avg) def calc_average(total, num): return total / num def isInvalidScore(score): status = True  if score < 0 or score > 100: status = True  else: status = False  return status
