Answer

n = int(input("Enter a number: "))
p = n
s = 0

while n > 0:
    d = n % 10
    s = s + d
    n = n // 10

if p % s == 0:
    print(p, "is a Niven Number")
else:
    print(p, "is not a Niven Number")

Output

Enter a number: 126
126 is a Niven Number

Enter a number: 167
167 is not a Niven Number
