Answer: Secret Code #224

The secret message says:

OAK

The secret note decoded: OAK
The note, decoded.

Letter by letter

Secret letterLPZ
Real letterOKA

Decode it with Python

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

secret = "LZP"
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:

OAK

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.
