Python Program to Check Armstrong Number

Armstrong number:
A number is called Armstrong number if it is equal to the sum of the cubes of its own digits.
For example: 153 is an Armstrong number since 153 = 1*1*1 + 5*5*5 + 3*3*3.

The Armstrong number is also known as narcissistic number.

See this example:

1. num = int(input("Enter a number: "))  
2. sum = 0  
3. temp = num  
4.   
5. while temp > 0:  
6.    digit = temp % 10  
7.    sum += digit ** 3  
8.    temp //= 10  
9.   
10. if num == sum:  
11.    print(num,"is an Armstrong number")  
12. else:  
13.    print(num,"is not an Armstrong number")  

Output:
