How to check if a number is armstrong number or not in Python

Answer 1

# An Armstrong number of three digits is an integer that the sum
# of the cubes of its digits is equal to the number itself

# 371 is an Armstrong number: 3**3 + 7**3 + 1**3 = 371

n = 371
summ = 0

tmp = n

while n != 0:
    reminder = n % 10
    n //= 10
    summ += reminder * reminder * reminder

if summ == tmp:
    print(tmp, 'is an Armstrong number')
else:
    print(tmp, 'is not an Armstrong number')


'''
run:

371 is an Armstrong number
