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
