There is a close connection between codes and computers. Below I have made a very simple code to decrypt a Caesar shift. It will give all possible combinations, and you then just have to find the one which makes sense! You can run this Python code here.
SYMBOLS = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ' print('CAESAR SHIFT DECRYTION') print('ENTER THE CODE YOU WANT TO DECRYPT, (USE CAPITAL LETERS)') code = input('>') for key in range(1,26): translated = '' for letter in code: if letter in SYMBOLS: num=SYMBOLS.find(letter) num = num-key if num<0: num = num+26 translated = translated + SYMBOLS[num] print(key, translated)
