This program inputs a user score in % and outputs a letter grade.

scale used is

90 or greater is an A

Less than 90 but 80 or greater is a B

Less than 80 but 70 or greater is a C

Less than 70 but 60 or greater is a D

Less than 60 is an F

def convert_grade_to_letter(number_grade): letter_grade = 'F' if number_grade >= 90: letter_grade = 'A' elif number_grade >= 80: letter_grade = 'B' elif number_grade >= 70: letter_grade = 'C' elif number_grade >= 60: letter_grade = 'D'

return letter_grade

def main(): try: number_grade = int(input("Input number grade: ")) number_grade = int(number_grade)

    if number_grade <= 0 or number_grade >= 101:
        raise ValueError("invalid data")
except ValueError as err:
    print("invalid data")

    if number_grade >= 101:
        print("{}".format(err))
    elif number_grade <= -1:
        print("{}".format(err))
    else:
        letter_grade = convert_grade_to_letter(number_grade)
    convert_grade_to_letter(number_grade)
    print("Letter grade: " + letter_grade)

main()

in this program I'm trying to make it so that it only has one output ex. Letter Grade: A invalid data should not pop up when I insert 1000 only invalid data should pop up
