6. Determine whether a number is a perfect number, an Armstrong number, or a palindrome.

Python

num = int(input("Enter a number: "))

 

# Check for perfect number

sum_factors = 0

for i in range(1, num):

    if num % i == 0:

        sum_factors += i

if sum_factors == num:

    print(num, "is a perfect number")

 

# Check for Armstrong number

order = len(str(num))

temp = num

sum_digits = 0

while temp > 0:

    digit = temp % 10

    sum_digits += digit ** order

    temp //= 10

if num == sum_digits:

    print(num, "is an Armstrong number")

 

# Check for palindrome

temp = num

reverse = 0

while temp > 0:

    remainder = temp % 10

    reverse = (reverse * 10) + remainder

    temp //= 10

if num == reverse:

    print(num, "is a palindrome")
