Answer: Secret Code #205

The secret message says:

OCEAN

Letter by letter

Secret letter	L	M	V	X	Z
Real letter	O	N	E	C	A

Decode it with Python

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

secret = "LXVZM"
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:

OCEAN
