Create a program that asks the user for an age. It tells them their grade (9, 10, 11 or 12) based on their response. Python : age = (int(input("How old are you?")))

if (age == 14 or age ==15):
    print ("you are in grade 9")

    if (age == 15):
        print("or")

        if (age == 15 or age == 16):
            print ("you are in grade 10")

            if (age == 16):
                print("or")

                if (age == 16 or age == 17):
                    print ("you are in grade 11")

                    if (age == 17):
                        print ("or")

                        if (age == 17 or age == 18):
                            print ("you are in grade 12")
