基于Regex-python规则的eliza实现

Question

import random
import re

rules=[["(.*)hello(.*)",["Hi there. Please state your problem"]],
           ["(.*)name(.*)",["Great, good to know","I am not interested 
        in names"]],
  ["(.*)sorry(.*)",["please don't apologize","Apologies are not necessary","What feelings you have when you apologize?"]],
 ["(.*)",["Very interesting","I am not sure I understand you fully","Please continue",
         "Do you feel strongly about discussing such things?","\\2"]]]

grammar = {
"am": "are",
"was": "were",
"i": "you",
"i'd": "you would",
"i've": "you have",
"i'll": "you will",
"my": "your",
"are": "am",
"you've": "I have",
"you'll": "I will",
"your": "my",
"yours": "mine",
"you": "me",
"me": "you"
}

def correction(word):
character=word.lower().split()
for i, j in enumerate(character):
    if j in grammar:
        character[i]=grammar[j]
return " ".join(character)

def test(sentence):
for pattern, message in rules:
    match=re.match(pattern,sentence.rstrip(".!"))
    if match:
        response = random.choice(message)
        temp = " " + correction(match.group())
        response2 = re.sub(r"\\2",temp,response)
        return response2
      else:
        recall=random.choice(message)
        return recall



while True:
sentence =input("You: ")
print("JBot: " + test(sentence))

    if sentence == "quit":
    break

在这个简单的eliza实现中，有一个名为rule的列表，其中包含一组模式和相应的响应。如果模式匹配或输入了任何不在规则（最后一条规则）中的内容，则该代码应该获得随机响应。你知道吗

代码现在只输出所有输入语句的"Hi, there. Please state your problem"。为什么会这样？？你知道吗

如果您输入了规则中匹配的句子，那么它将以相应的响应进行回复。假设一个规则如下：'(.*)就像(.*)'，[“你在{0}和{1}之间看到了什么储备？”]]，如果输入是"Cats are like dogs"，那么响应应该是这样的，你看到猫和狗之间有什么相似之处？因此，它需要从比赛中选出一组人，并在各自的回答中给出位置。你知道吗

Answer 1

我已经修复了您的代码，现在应该可以正常工作了：

备注：

• test函数的循环中的else将在每次迭代时退出循环，因此您将无法浏览所有规则、语法。我把它放在for之后，这将强制首先检查每个规则，然后再选择默认的随机选择答案。你知道吗

代码：

import random
import re

rules=[["(.*)hello(.*)",["Hi there. Please state your problem"]],
           ["(.*)name(.*)",["Great, good to know","I am not interested in names"]],
  ["(.*)sorry(.*)",["please don't apologize","Apologies are not necessary","What feelings you have when you apologize?"]],
 ["(.*)",["Very interesting","I am not sure I understand you fully","Please continue",
         "Do you feel strongly about discussing such things?","\\2"]]]

grammar = {
"am": "are",
"was": "were",
"i": "you",
"i'd": "you would",
"i've": "you have",
"i'll": "you will",
"my": "your",
"are": "am",
"you've": "I have",
"you'll": "I will",
"your": "my",
"yours": "mine",
"you": "me",
"me": "you"
}

def correction(word):
  character=word.lower().split()
  for i, j in enumerate(character):
      if j in grammar:
          character[i]=grammar[j]
  return " ".join(character)

def test(sentence):
  for pattern, message in rules:
      match=re.match(pattern,sentence.rstrip(".!"))
      if match:
          response = random.choice(message)
          temp = " " + correction(match.group())
          response2 = re.sub(r"\\2",temp,response)
          return response2
  recall=random.choice(random.choice([r[1] for r in rules]))
  return recall



while True:
  sentence =input("You: ")
  print("JBot: " + test(sentence))
  if sentence == "quit":
        break

输出：

You: 'hello'
JBot: Hi there. Please state your problem
You: "i don't have a name"
JBot: Great, good to know
You: "i am so sorry"
JBot: What feelings you have when you apologize?
You: "help me"
JBot: Do you feel strongly about discussing such things?

The outputs are so funny it has literally made my day.
