A positive number is called an Armstrong number if it is equal to the sum of the cubes of its numbers, for example 0, 1, 153, 370, 371, 407, etc.
In other words, the following equation will be verified
xy..z = xn + yn + ….. + zn
n is the number of digits
For example, 370 is a 3-digit Armstrong number
370 = 33 + 73 + 03
= 27 + 343 + 0
= 370
Now, let’s see the implementation of Armstrong’s number in Python.
Program to check if the given number is an Armstrong number
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 |
# Python program to check if the number provided by the user is an Armstrong number or not # take input from the user num = int(input("Enter a number: ")) # initialize sum sum = 0 # find the sum of the cube of each digit temp = num while temp > 0: digit = temp % 10 sum += digit ** 3 temp //= 10 # display the result if num == sum: print(num,"is an Armstrong number") else: print(num,"is not an Armstrong number") |
Output:
|
1 2 3 4 |
Enter a number: 370 370 is an Armstrong number |
