Check if a number is an Armstrong number Program Code

# Armstrong number: 153 = 1³ + 5³ + 3³ = 153
num = int(input("Enter a number: "))
original = num
sum_of_powers = 0

# Count digits
num_str = str(num)
num_digits = len(num_str)

# Calculate sum of digits raised to power
for digit in num_str:
    sum_of_powers += int(digit) ** num_digits

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