Question

I am making a program that takes a sentence and garbles it, until run through a “degarbler”

Theres probably a better way to do this, but I would appreciate it if everyone would show me how to fix what I am doing wrong

def sencoder (sentence):
    sentence = sentence.replace ("a","h")
    sentence = sentence.replace ("s","j")
    sentence = sentence.replace ("d","k")
    sentence = sentence.replace ("f","l")
    sentence = sentence.replace ("b","g")
    sentence = sentence.replace ("z","t")
    sentence = sentence.replace ("q","y")
    sentence = sentence.replace ("w","u")
    sentence = sentence.replace ("e","i")
    sentence = sentence.replace ("r","o")
    sentence = sentence.replace ("x","p")
    sentence = sentence.replace ("c","b")
    sentence = sentence.replace ("v","n")
    sentence = sentence.replace ("m","m")
    print sentence

def decoder (sentence):
    sentence = sentence.replace ("h","a")
    sentence = sentence.replace ("j","s")
    sentence = sentence.replace ("k","d")
    sentence = sentence.replace ("l","f")
    sentence = sentence.replace ("g","b")
    sentence = sentence.replace ("t","z")
    sentence = sentence.replace ("y","q")
    sentence = sentence.replace ("u","w")
    sentence = sentence.replace ("i","e")
    sentence = sentence.replace ("o","r")
    sentence = sentence.replace ("p","x")
    sentence = sentence.replace ("b","c")
    sentence = sentence.replace ("n","v")
    sentence = sentence.replace ("m","m")
    print sentence

sentence = ""
choice = raw_input ("Do you want to decode or encode: ").lower()   
while sentence != "quit":
    sentence = raw_input("Enter the code: ")
    if choice == "encode":
        decoder(sentence)
    elif choice == "decode":
        sencoder(sentence)
    else:
        print "Please make a valid decision"

Answer 1

Here is a hint: Use the translate method instead.

>>> import string

>>> t = string.maketrans("abcdef", "bcdefa")
>>> "abracadabra".translate(t)
'bcrbdbebcrb'

>>> t2 = string.maketrans("bcdefa", "abcdef")
>>> "bcrbdbebcrb".translate(t2)
'abracadabra'
