Decode it with Python

This program does the decoding for you. Change the secret and the code to crack other messages!

secret = "ILYLG SFT"
message = ""

for letter in secret:
    if letter.isalpha():
        position = ord(letter) - ord("A")
        message = message + chr(ord("Z") - position)
    else:
        message = message + letter

print(message)

When you run it, it prints:

ROBOT HUG

Did you know? The mirror code is thousands of years old. It was first used with the Hebrew alphabet, where the first letter swaps with the last, the second with the second-to-last, and so on.
