Trying to make an encrypted message system
Hey so I'm new to Python and this app is helping me learn fast. I am wanting to make a module to encrypt messages and to decrypt messages. I'm having some difficulty with solving this. So it would help if someone could have some steps to help me out. Thanks :) love this app though

Try bit flipping... https://github.com/cclauss/Ten-lines-or-less/blob/master/bit_filpper.py

Another option: translate (here's a caesar cipher from stackoverflow. )
#! Python2 import string def caesar(plaintext, shift): alphabet = string.ascii_lowercase shifted_alphabet = alphabet[shift:] + alphabet[:shift] table = string.maketrans(alphabet, shifted_alphabet) return plaintext.translate(table)
For a simple two-way cipher, rot13 comes built in, using the encode method of str types.
>>> print "Gur rntyr syvrf ng zvqavtug".encode("rot13") 'The eagle flies at midnight'
Thank you so much everyone! This has helped :)

Thanks so much everyone this was a good learning experience! I made this system with your examples.
import string char_list = list(string.ascii_letters) + list(string.digits) + list(string.punctuation) def encrypt(message, key): alphabet = string.ascii_letters shifted_alphabet = alphabet[key:] + alphabet[:key] table = string.maketrans(alphabet, shifted_alphabet) return message.translate(table) def decrypt(message, key): alphabet = string.ascii_letters shifted_alphabet = alphabet[-key:] + alphabet[:-key] table = string.maketrans(alphabet, shifted_alphabet) return message.translate(table)

@Spencer1221 If you put that code inside triple back ticks (
`) it will show as formatted code:
``` your code here ```
Oh ok thanks @Webmaster4o

now: make your code work with both upper and lowercase alphabet!
