In this Python example you are going to learn how to find a number is an Armstrong number or not. An “Armstrong number” is a number that is equal to the sum of the nth powers of its individual digits. For example, 371 is an Armstrong number where it has 3 digits and 337313 = 371
Here is the Python script for finding the Armstrong number.

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 |
print("Enter the number") #get the number number = int(input()) #store it in a temp temp = int(number) Sum = 0 #loop till the quotient is 0 while(temp != 0): rem = temp % 10 #find reminder Sum = Sum + (rem * rem * rem) #cube reminder and add it to the Sum temp = temp / 10 #find quotient, if 0 then loop again #if the entered number and the Sum value matches, it is an Armstrong number if(number == Sum): print ("Armstrong Number") else: print ("Not an Armstrong Number") |
The above code is self explanatory, just read the comments to understand it.
Below are the Armstrong number, use these number to test this above code:
1. 153
2. 371
3. 407
And if you are looking for web based Python CGI Script to test Armstrong number, here it is:
