I'm learning Python 3 at the moment, so to test the skills I've learned, I am trying the puzzles at Python Challenge.
I've created some code to solve the 2nd puzzle here. it works, but I think that the way I've done it is very convoluted. Any suggestions on how to solve the puzzle in a simpler way?
(The code basically needs to substitute each letter in a message to the letter 2 spaces to the right of it, such as E->G.)
import string alphabet = string.ascii_lowercase letter=0 replaceLetter = 2 times=1 message = input() newMessage='' while times < 26: newMessage = message.replace(alphabet[letter], str(replaceLetter)+',') message = newMessage letter = letter + 1 replaceLetter = replaceLetter + 1 time = times + 1 if letter == 26: times = 0 break newMessage = message.replace('26'+',', 'a') message = newMessage newMessage = message.replace('27'+',', 'b') message = newMessage number = 25 message = newMessage while times < 26: newMessage = message.replace(str(number)+',', str(alphabet[number])) message = newMessage letter = letter + 1 number = number - 1 time = times + 1 if number == -1: times = 0 break print(newMessage)
