17.Write a function called sum_digits that is given an integer num and returns the sum of the digits of num.

def sum_digit(num):

    sum1=0

    while(num!=0):

        sum1=sum1+num%10

        num=num//10

    return(sum1)

num=int(input("enter the integer number:"))

sum1=sum_digit(num)

print("the sum of %d digits are =%d"%(num,sum1))

output:
