Secret Code Maker 🗝️

Every letter has a secret number. ord() tells you the number, chr() turns a number back into a letter:

print(ord("a"))            # ➜ 97
print(chr(98))             # ➜ b
print(chr(ord("a") + 1))   # ➜ b   (one letter along!)

See what happened there? Take a letter, get its number, add 1, turn it back into a letter. You just shifted the alphabet. 🔤➡️

Do that to every letter in a word and you've built a cipher — Julius Caesar used exactly this trick to send secret orders 2000 years ago. 🏛️

To build up a new string letter by letter, start empty and glue:

secret = ""
secret = secret + "q"      # ➜ "q"

Your mission

Encode the word python by shifting every letter forward by one, then print the secret message.

Do it right and python becomes... something no one can read. 🕵️‍♀️
