A Program to Check Armstrong Number

In this example, we are giving a program to check whether an n-digit integer is an Armstrong number or not. An Armstrong number is a number that is the sum of its own digits each raised to the power of the number of digits.

Program to check Armstrong number:

# Check Armstrong number
num = int(input('Enter a number: '))
order = len(str(num))
sum = 0
temp = num
while temp > 0:
  digit = temp % 10
  sum += digit ** order
  temp //= 10
if num == sum:
  print(num,"is an Armstrong number")
else :
  print(num,"is not an Armstrong number")

Output:

Enter a number: 153
153 is an Armstrong number

Enter a number: 737
737 is not an Armstrong number
