# Program to find the sum of all digits of given number in Python

Suppose we have a number num, we have to find the sum of its digits. We have to solve it without using strings.

So, if the input is like num = 512, then the output will be 8, as 8 = 5 + 1 + 2.

tput will be 8, as 8 = 5 + 1 + 2. To solve this, we will follow these steps −

- sum:= 0
- while num is not same as 0, do
- sum := sum + (num mod 10)
- num:= quotient of num/10

- return sum

Let us see the following implementation to get better understanding −

## Example

class Solution: def solve(self, num): sum=0 while(num!=0): sum = sum+int(num%10) num=int(num/10) return sum ob = Solution() print(ob.solve(512))

## Input

512

## Output

8
