编辑文本文件 [英] editing a text file
问题描述
你好，
我也很喜欢python表单和编程
我有一个文本文件，我需要提取几个单词标题中的数据（由3行组成）并在整个文件（由150行组成的文件）中搜索与特定id相关的关键字TEXT1，TEXT2，TEXT3并得到TEXT1，TEXT2的WRITES的总和，TEXT3
ex：输入文件将如下
Windows 2000文本文本文本文本文本文本
343434文本文本文本文本文本文本代码textplayback
文本文本文本文本文本开始检查文本..
文本文本文本文本文本343434 ，文字ID：504181，文件：text1，Write_0 = 24
文本文本文本文本文本343434，文本ID：504182，文件：text1，Write_0 = 20
文本文本文本文本文本343434，文本ID：504183，文件：text1，Write_0 = 21
文本文本文本文本文本343434，文本ID：504181，文件：text2，Write_0 = 29
文本文本文本文本343434，文本ID：504182，文件：text2，Write_0 = 20

文本文本文本文本文本343434，文本ID：504183，文件：text3，Write_0 = 23
输出应该如下：
343434 textplayback，开始检查 - >这是来自标题
文本ID：504181：（24 + 21 + 29）之和即27 ---->这是整个文件搜索的结果
请帮助我这方面
提前感谢您的帮助

我没有太多时间思考整个过程，但似乎有些基本概念会有所帮助。这是我刚刚完成的一个会话，并评论说明了如何访问某些值。你会发现python通常有很多不同的方法可以实现一个给定的方法，并且总是有一种更紧凑的方式（除非你从这里的几个真正的专业人士那里得到它）。这些只是想法。
I haven''t had a lot of time to think through the entire process, but it seems like some basic concepts would be helpful. Here is a session I just ran through and commented that shows how some of the values could be accessed. You will find with python that there are generally dozens of different ways to accomplish a given and there is always a more compact way (unless you get it from a couple of the real pros here). These are just ideas.
bluemountain，
希望dshimer的建议能让您找到解决方案。以下使用 re 模块。
bluemountain,
Hopefully dshimer''s suggestions will enable you to find a solution. The following makes use of the re module.
