Python Program to Find Armstrong Number in an Interval

 # 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)

Output
