# 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

Live Demo

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
