Complete the code segment to check whether the number is an Armstrong number or not.Armstrong Number:

Here’s a Python code segment that checks whether a number is an Armstrong number or not:

# Function to check if a number is an Armstrong number
def is_armstrong_number(num):
    # Convert the number to string to iterate through digits
    str_num = str(num)
    # Calculate the number of digits
    num_digits = len(str_num)
    
    # Calculate the sum of the powers of its digits
    sum_of_powers = sum(int(digit) ** num_digits for digit in str_num)
    
    # Check if the sum of powers is equal to the original number
    return sum_of_powers == num

# Example usage
number = int(input("Enter a number: "))
if is_armstrong_number(number):
    print(f"{number} is an Armstrong number.")
else:
    print(f"{number} is not an Armstrong number.")

Just copy and paste this code into your Python environment, and it will check if the provided number is an Armstrong number or not when you run it.
