循环运行.txt文件的目录

发布于 2025-01-14 05:49:09 字数 628 浏览 4 评论 0原文

我想编写一个代码来运行包含文本文件的大目录中的每个 .txt 文件。我想打印输入单词出现的上下文（即行）的每一次出现，以及文档的标题。

假设单词“cat”出现在 5/10 文档中。我想打印出现“猫”的每一个句子。

这是我到目前为止的代码。它确实“有效”，但它只打印输入单词在一个文档中的出现，而不是在每个文档中。

谢谢你！

import os
import re


dir1=("/my directory/")

for txt in os.listdir(dir1):
    with open (dir1+"/"+txt, "r", encoding="utf8") as f_obj:
        contents=f_obj.readlines()
        word=input("Type the word whose context you want to find:")
        for line in contents:
            if re.search(word,line):
                print("Title of document:", f_obj.name)
                print("Context of use:", line)

原文

I want to write a code that runs each .txt file in a large directory containing text files. I want to print every single occurrence of the context (i.e. line) in which the input word appears in, as well as the title of the document(s).

Let's say the word 'cat' appears in 5/10 documents. I want to print every single sentence in which 'cat' appears in.

Here's the code I have so far. It does "work", but it only prints the occurrence of the input word in one document, not in every single document.

Thank you!

import os
import re


dir1=("/my directory/")

for txt in os.listdir(dir1):
    with open (dir1+"/"+txt, "r", encoding="utf8") as f_obj:
        contents=f_obj.readlines()
        word=input("Type the word whose context you want to find:")
        for line in contents:
            if re.search(word,line):
                print("Title of document:", f_obj.name)
                print("Context of use:", line)

您可以将输入单词的声明移到 for 循环之外，如下所示：

import os
import re


dir1=("/my directory/")

word=input("Type the word whose context you want to find:")

for txt in os.listdir(dir1):
    with open (dir1+"/"+txt, "r", encoding="utf8") as f_obj:
        contents=f_obj.readlines()
        for line in contents:
            if re.search(word,line):
                print("Title of document:", f_obj.name)
                print("Context of use:", line)

现在，每个文档将使用相同的输入单词。请参阅下面的示例输出，了解应用此更改的情况（并在我的两个文本文件“t.txt”和“3.txt”中检测cat）

Type the word whose context you want to find:cat
Title of document: /my directory/t.txt
Context of use: cat on a bat

Title of document: /my directory/t.txt
Context of use: bat on a cat

Title of document: /my directory/3.txt
Context of use: cat on a bat

Title of document: /my directory/3.txt
Context of use: cat on a mat

You could move the declaration of the input word outside of the for-loop, like this:

import os
import re


dir1=("/my directory/")

word=input("Type the word whose context you want to find:")

for txt in os.listdir(dir1):
    with open (dir1+"/"+txt, "r", encoding="utf8") as f_obj:
        contents=f_obj.readlines()
        for line in contents:
            if re.search(word,line):
                print("Title of document:", f_obj.name)
                print("Context of use:", line)

Now the same input word will be used for each of the documents. See below for example output with this change applied (and detecting cat across my two text files "t.txt" and "3.txt")

Type the word whose context you want to find:cat
Title of document: /my directory/t.txt
Context of use: cat on a bat

Title of document: /my directory/t.txt
Context of use: bat on a cat

Title of document: /my directory/3.txt
Context of use: cat on a bat

Title of document: /my directory/3.txt
Context of use: cat on a mat
