Determine whether a number is a perfect number, an Armstrong number or a palindrome. code example

Example 1: Take n as input and check which ones are Armstrong number using a function in the range 1 to n in python

num = 370
# Changed num variable to string, 
# and calculated the length (number of digits)
order = len(str(num))
# initialize sum
sum = 0
# find the sum of the cube of each digit
temp = num
while temp > 0:
   digit = temp % 10
   sum += digit ** order
   temp //= 10
# display the result
if num == sum:
   print(num,"is an Armstrong number")
else:
   print(num,"is not an Armstrong number")
#Output-- 370 is an Armstrong number

Example 2: armstrong number in python

# Program to check Armstrong numbers in a certain interval

lower = 100
upper = 2000

for num in range(lower, upper + 1):

   # order of number
   order = len(str(num))
    
   # initialize sum
   sum = 0

   temp = num
   while temp > 0:
       digit = temp % 10
       sum += digit ** order
       temp //= 10

   if num == sum:
       print(num)
