# Python Program to check whether a given number is Armstrong or not

**Program to check whether a given number is Armstrong or not**

A number is said to be an Armstrong if the sum of each digit’s cube of a given number equals the original number.

**Example:**

Given number 153 1*1*1 + 5*5*5 + 3*3*3 = 153 So the given number is Armstrong.

The following is a source code to detect Armstrong number in Python:

#Program to a given number is Armstrong

#Take user input

number = int(input(“Enter the number:”))

#Initialize sum

sum = 0

#Compute the sum of cube of each digit

temp = number

while(temp > 0):

digit = temp%10

sum += digit**3

temp *//= 10*

#Check the result

if number == sum:

print(number, “is an Armstrong number.”)

else:

print(number, “is not an Armstrong number.”)
