How do I change the python code below to calculate and output the sum of all digits of the input number, based on the problem below?
n = int(input())
length = 0
while n > 0:
n //= 10
length += 1
print(length)

You'd want `length += n % 10` but I'd instead call it `total` since that's more accurate. You'd also want to do that *before* dividing by 10 or you'll be off by a digit – Cory Kramer Jun 04 '21 at 19:39

n = input()
sum = 0
for char in n:
if char.isdigit():
sum += int(char)
print(sum)

I keep getting this with your suggestion: Traceback (most recent call last): File "/usercode/file0.py", line 6, in
sum += char TypeError: unsupported operand type(s) for +=: 'int' and 'str' – captaincaveman1729 Jun 04 '21 at 19:43 -
@captaincaveman1729 oops … I should test my code before posting it - should work now – TheEagle Jun 04 '21 at 19:59

Thanks so much! it worked. I'm very new to python and coding at large, so now I have to understand what you did... good problems! – captaincaveman1729 Jun 04 '21 at 20:01
