title: How do I loop back to a part of my program in python?
body: <p>So I've been trying to make a python program for a cypher my firend and I did (joined 2 different cyphers) and I've been stuck trying to make it easy to encrypt different string without opening and closing the program every time. I'm using python 3.2 on a 64-bit windows 7 computer.</p>
  
  <p>Here is my code (please also give me tips to polish it a bit): </p>
  
  <pre><code>#!/usr/bin/python
  
  #from string import maketrans   # Required to call maketrans function.
  
  print ("Welcome to the Rotten Bat encription program. Coded in python by Diego Granada")
  answer = input("Please enter the password: ")
  if answer == 'raindrops':
      print("Password accepted")
  else:
      print ("Incorrect password. Quiting")
      from time import sleep
      sleep(3)
      exit()
  intab = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz"
  outtab = "N9Q2T1VWXYZ7B3D5F8H4JK60n9pq2st1vwxyz7b3d5f8h4jk60"
  
  message = input("Put your message here: ")
  
  print(message.translate(dict((ord(x), y) for (x, y) in zip(intab, outtab))))
  
  print ("Thank you for using this program")
  
  input()
  </code></pre>
