用python写一个能聊天的人工智能

好的,让我们来写一个基于Python的简单人工智能聊天机器人。
首先,我们需要导入Python的NLTK(自然语言处理工具包):
```
import nltk
nltk.download('punkt')
```
接下来,我们需要定义一些对话规则,这些规则将帮助我们的机器人理解用户的输入并给出合适的响应。在这个例子中,我们将使用一个简单的字典来存储这些规则:
```
rules = {'if you (.*)': ['I am sorry, I cannot {0}',
'Why do you think I {0}'],
'I want (.*)': ['What would it mean if you got {0}',
'Why do you want {0}',
"What's stopping you from getting {0}"],
'do you remember (.*)': ['Did you think I would forget {0}',
"Why haven't you been able to forget {0}",
'What about {0}', 'Yes .. and?'],
'do you think (.*)': ['if {0}? Absolutely.',
'No chance'],
'if (.*)': ["Do you really think it's likely that {0}",
'Do you wish that {0}',
'What do you think about {0}',
'Really--if {0}']
}
```
这些规则使用正则表达式来匹配用户的输入。例如,如果用户输入“if you can't beat them, join them”,机器人将匹配到“if you”这个规则,并回复“I am sorry, I cannot join them”或者“Why do you think I should join them”。
接下来,我们需要定义一个函数来处理用户的输入并给出响应:
```
import re
import random
def get_response(message):
for pattern, responses in rules.items():
match = re.search(pattern, message)
if match:
response = random.choice(responses)
return response.format(*[match.group(i) for i in range(1, len(match.groups())+1)])
return "I'm sorry, I don't understand what you're asking."
```
这个函数将遍历定义的规则,查找与用户输入匹配的规则,并随机选择一个响应返回给用户。如果没有找到匹配的规则,机器人将回复“I'm sorry, I don't understand what you're asking.”。
现在我们已经有了一个简单的人工智能聊天机器人。我们可以测试一下它的功能:
```
while True:
message = input('You: ')
response = get_response(message)
print('Bot: ' + response)
```
这个代码将启动一个无限循环,等待用户输入。每当用户输入一条消息,机器人将返回一个响应。我们可以通过输入“exit”来退出循环。
这只是一个简单的例子,但是你可以使用更复杂的规则和算法来创建一个更强大的人工智能聊天机器人。
