def digit_sum(n): m = str(n) final_product = 0 numbers =  for c in m: numbers.append(c) for i in numbers: l = 0 numbers[l] == int(i) l = l + 1 for i in numbers: final_product = final_product + i
Got the error message " Oops, try again. Does your digit_sum function take exactly one argument (a positive integer)? Your code threw a "unsupported operand type(s) for +: 'int' and 'str'" error." What am I doing wrong?
