帮助倒置字典 [英] Help with inverted dictionary

问题描述

我是Python的新手，我正在努力。我有一个文本文件（* .txt）和

几千个条目，每个条目都在自己的行上（类似于手机

书）。我如何创建一个脚本来创建类似于反转的字母，这将允许我调用robert字典。并创建一个新文本

包含robert的所有行的文件？

非常感谢。

I''m new to Python and I''m struggling. I have a text file (*.txt) with
a couple thousand entries, each on their own line (similar to a phone
book). How do I make a script to create something like an inverted
dictionary that will allow me to call "robert" and create a new text
file of all of the lines that contain "robert"?
Thanks so much.

推荐答案

你好，


首先我不太清楚你的问题，但你可以做以下

步骤：

1.将文件转换为列表（list1）

2.使用正则表达式捕获list1的每个成员中的''robert''并添加到

list2

3.将list2转换为文件

Hello,

First I''m not so clear about your problem, but you can do the following
steps:
1. Transform your file into list (list1)
2. Use regex to capture ''robert'' in every member of list1 and add to
list2
3. Transform your list2 into a file

pujo

import re

name =" Robert"

f = file（''phonebook.txt''，''r''）

lines = [line.rstrip（" \ n"）for f.readlines（）]中的行

pat = re.compile（name，re.I）

related_lines = [行中行的行如果pat.search（行）]


然后你将related_lines中的行写入文件。我不是真的好吗？b $ b把文字写到文件上很多，嗯，是的。

import re
name = "Robert"
f = file(''phonebook.txt'',''r'')
lines = [line.rstrip("\n") for line in f.readlines()]
pat = re.compile(name, re.I)
related_lines = [line for line in lines if pat.search(line)]

And then you write the lines in related_lines to a file. I don''t really
write text to files much so, um, yeah.

好的，所以我的问题是我有一个包含所有这些实例的文本文件，

例如关于动物的5000个事实。我需要浏览文件

并将包含单词lion的所有事实（行）放入一个名为lion.txt的
文件中。如果我遇到一个尚未存在

文件的动物或其他单词，我需要为该单词创建一个文件并将该单词的所有实例放入

那个文件。我意识到这应该可以创建30,000个左右的文件。任何帮助都将非常值得赞赏。谢谢。 Reece

OK, so my problem is I have a text file with all of these instances,
for example 5000 facts about animals. I need to go through the file
and put all of the facts (lines) that contain the word lion into a file
called lion.txt. If I come across an animal or other word for which a
file does not yet exist I need to create a file for that word and put
all instances of that word into that file. I realize that this should
probably create 30,000 files or so. Any help would be REALLY
appreciated. Thanks. Reece
