In this tutorial we are going to learn about finding the Sum of Digits in a Number in Python.

Python Program to Find the Sum of Digits in a Number

n=int(input("Enter a number:"))
tot=0
while(n>0):
   dig=n%10 
   tot=tot+dig 
   n=n//10 
print("The total sum of digits is:",tot)

Explanation

1. User must first enter the value and store it in a variable.
2. The while loop is used and the last digit of the number is obtained by using the modulus operator.
3. The digit is added to another variable each time the loop is executed.
4. This loop terminates when the value of the number is 0.
5. The total sum of the number is then printed.
