Python Program to Find Armstrong Number in an Interval – 2023

Hey guys, in this blog we will see a Python Program to Find Armstrong Number in an Interval.

Code

# Program to check Armstrong numbers in a certain interval

lower = 100
upper = 5000

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

153
370
371
407
1634

Here we have simply defined a lower and upper bound of the range in which we need to find the Armstrong numbers. Check out this blog to understand Armstrong numbers: Python Program to Check Armstrong Number
