Check Armstrong number (Narcissistic number) Program Code

# Armstrong number: sum of cubes of digits equals number
num = int(input("Enter a number: "))
original = num
sum_cubes = 0
temp = num

# Count digits
count = 0
while temp > 0:
    count += 1
    temp //= 10

# Calculate sum of digits raised to power count
temp = num
while temp > 0:
    digit = temp % 10
    sum_cubes += digit ** count
    temp //= 10

if original == sum_cubes:
    print(f"{original} is an Armstrong number")
else:
    print(f"{original} is NOT an Armstrong number")
