Welcome back, In this tutorial we are going to learn how to write a program in python to check a given input number is Armstrong or not?
So before moving directly on the writing program I will recommend you please first know :

What is Armstrong Number?
- It is a number which is equal to the sum of cube of its digits.
- For eg: 153, 370 etc.
Lets see it practically by calculating it,
Suppose I am taking 153 for an example
First calculate the cube of its each digits
1^3 = (1*1*1) = 1
5^3 = (5*5*5) = 125
3^3= (3*3*3) = 27
Now add the cube
1+125+27 = 153
It means 153 is an Armstrong number.
Ok, Then move on the program when you have cleared concept 🙂
Program to check a number is Armstrong or not in python programming language
i=0
result=0
n = int(input("please give a number : "))
number1 = n
temp = n
while n!=0:
n = (n//10)
i=i+1;
while number1!=0:
n=number1%10
result=result+pow(n,i)
number1=number1//10
if temp==result:
print("number is armstrong")
else:
print("number is not armstrong") Output:
