# Python Program To Check Armstrong Number

#### What is Armstrong number?

Armstrong number in a given number base b is a number that is the sum of its own digits each raised to the power of the number of digits.

#### Example

**153** = 1^{3} + 5^{3} + 3^{3 }= 1+125+27 = 153

### Program

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 | # armstrong number in python # take input from the user num = int(input("Enter a number: ")) # find the length of num and this length is used in power power = len(str(num)) # set count = 0 initially count = 0 # now take a temprory num temp = num while temp > 0: # take a last digit from the number digit = temp % 10 # add this number with the power in count count += digit ** power # now remove the last digit from temp(num) temp //= 10 # print result if num == count: print(num,"is an Armstrong number") else: print(num,"is not an Armstrong number") # armstrong number in python - docodehere.com |

#### Output

Enter a number: 153
153 is an Armstrong number
