Python Program to Check Armstrong Number

Updated: May 27, 2021


Armstrong number is a number that is equal to the sum of cubes of its digits. For example 0, 1, 153, 370, 371 and 407 are the Armstrong numbers.

Program:

n = int(input("Enter a number: "))

sum = 0

a = n

while n > 0:

digit = n % 10

sum += digit ** 3

n //= 10

if a == sum:

print("Armstrong number")

else:

print("Not Armstrong number")


Output:

Enter a number: 153 Armstrong number
