 return string.translate(s, string.maketrans(old, new))</div>
<div>
class Rot13(webapp2.RequestHandler):

 self.response.out.write(form % {"text": text})</div>
<div> def get(self):
 self.write_form()</div>
<div> def post(self):
 user_text = self.request.get("text")</div>
<div> user_text = translate(str(user_text))
 #print user_text
 user_text = escape_html(user_text)</div>
<div> self.write_form(user_text)
