Question

Write a program to find the sum of all digits of the given number.

Answer 1

Extract the last digit using % 10, add it to sum, and remove it using // 10.

n = int(input("Enter any number: "))
sum_of_digits = 0

while n > 0:
    sum_of_digits += n % 10
    n //= 10

print("Sum of digits =", sum_of_digits)
