Question

我刚进入编码并进行查询。我正在为一个名为Sasha的聊天机器人编写脚本，但是我无法找到任何方法来解决句子中并非所有单词匹配的问题。说，我想让它以不同的方式检查日期，而不仅仅是说，＆＃39; date＆＃39;。我该怎么做呢？任何帮助表示赞赏。

Database =[

        ['hello sasha', 'hey there'],

        ['what is the date today', 'it is the 13th of October 2017'],

        ['name', 'my name is sasha'],

        ['weather', 'it is always sunny At Essex'],

        ]

while 1:
        variable = input("> ") 

        for i in range(4):
                if Database[i][0] == variable:
                        print (Database[i][1])

Answer 1

您可以使用'in'来检查列表中是否有某些内容，如下所示:(在伪代码中）

list = ['the date is blah', 'the time is blah']

chat = input('What would you like to talk about')

if chat in ['date', 'what is the date', 'tell the date']:
  print(list[0])

elif chat in ['time', 'tell the time']:
  print(list[1])

etc.

您应该考虑了解哪些词典，这对您有很大的帮助。

Answer 2

您可以使用dict将输入映射到答案

更新：添加正则表达式以匹配输入，但我认为你的问题更像是NLP问题。

import re
Database ={

        'hello sasha': 'hey there',

        'what is the date today':'it is the 13th of October 2017',

        'name': 'my name is sasha',

        'weather': 'it is always sunny At Essex',

        }

while 1:
        variable = input("> ") 
        pattern= '(?:{})'.format(variable )
        for question, answer in Database.iteritems():
            if re.search(pattern, question):
                 print answer

输出：

date
it is the 13th of October 2017

Answer 3

一个非常基本的答案是检查句子中的单词：

while 1:
    variable = input("> ") 

    for i, word in enumerate(["hello", "date", "name", "weather"]):
        if word in input.split(" "):  # Gets all words from sentence 
            print(Database[i][1])


    in: 'blah blah blah blah date blah'
    out: 'it is the 13th of October 2017'
    in: "name"
    out: "my name is sasha"

如何搜索和打印输入中的项目，python？
