聊天机器人Eliza 代码_eliza源码

Eliza是基于正则表达式替换的聊天软件，实现非常简单，以下是其Python代码：

from util import reflections
pairs = (
  (r'I need (.*)',
  ( "Why do you need %1?",
    "Would it really help you to get %1?",
    "Are you sure you need %1?")),
 
  (r'Why don\'t you (.*)',
  ( "Do you really think I don't %1?",
    "Perhaps eventually I will %1.",
    "Do you really want me to %1?")),
 
  (r'Why can\'t I (.*)',
  ( "Do you think you should be able to %1?",
    "If you could %1, what would you do?",
    "I don't know -- why can't you %1?",
    "Have you really tried?")),
 
  (r'I can\'t (.*)',
  ( "How do you know you can't %1?",
    "Perhaps you could %1 if you tried.",
    "What would it take for you to %1?")),
 
  (r'I am (.*)',
  ( "Did you come to me because you are %1?",
    "How long have you been %1?",
    "How do you feel about being %1?")),
 
  (r'I\'m (.*)',
  ( "How does being %1 make you feel?",
    "Do you enjoy being %1?",
    "Why do you tell me you're %1?",
    "Why do you think you're %1?")),
 
  (r'Are you (.*)',
  ( "Why does it matter whether I am %1?",
    "Would you prefer it if I were not %1?",
    "Perhaps you believe I am %1.",
    "I may be %1 -- what do you think?")),
 
  (r'What (.*)',
  ( "Why do you ask?",
    "How would an answer to that help you?",
    "What do you think?")),
 
  (r'How (.*)',
  ( "How do you suppose?",
    "Perhaps you can answer your own question.",
    "What is it you're really asking?")),
 
  (r'Because (.*)',
  ( "Is that the real reason?",
    "What other reasons come to mind?",
    "Does that reason apply to anything else?",
    "If %1, what else must be true?")),
 
  (r'(.*) sorry (.*)',
  ( "There are many times when no apology is needed.",
    "What feelings do you have when you apologize?")),
 
  (r'Hello(.*)',
  ( "Hello... I'm glad you could drop by today.",
    "Hi there... how are you today?",
    "Hello, how are you feeling today?")),
