# a heavy int is one where the average of the digits is greater than 7
# eg: 8678 is heavy because (8 + 6 + 7 + 8) / 4 = 7.25
#     8677 is not heavy because ( 8 + 6 + 7 + 7) / 4 = 7

def is_heavy(my_number, heaviness=7):
    # map each digit to a float and divide by the length
    digits = str(my_number)
    return sum(map(float, digits)) / len(digits) > heaviness
