    if total_sum >= 86:
        print('You received an A')
    
    elif total_sum >= 74:
         print('You received a B')
    
    elif total_sum >= 62:
         print('You received a C')
              
    elif total_sum >= 54:
         print('You received a D')
    
    else:
        print('You failed :(')
    
else:
    print('Something is not right!')     

What i want to do is to check each input to see if it is between 0 and 100, if not ask to enter again. What is the easiest way to do this? Thanks!

Anything that is repetitive is a candidate for a function. Below is a function vinput that takes the prompt as an argument and returns the validated input.

def vinput(prompt) :
    valid = False
    while not valid :
        try :
            temp = float(input(prompt))
            if temp<0 or temp>100:
                raise ValueError
            else :
                valid = True
        except ValueError :
            print('Invalid entry, try again')
    return temp

midterm1 = vinput('Enter score for midterm: ')

Thank you!
