python - 从包含python中URL列表的文本文件中打印文本文件中URL的内容

问题描述

我有一个包含 URL 列表的文本文件，我愿意在另一个文本文件中打印 URL 的内容，并将 URL 作为标题。我已经使用这个项目文件https://pypi.org/project/Wikipedia-API/来提取内容，但是我必须一个接一个地输入链接，我不想深入研究，因为我的列表是巨大的，每个文本文件至少有 3000 个链接。

谁能帮我解决这个问题，将不胜感激。

编辑：

我通过以下方式尝试过，但是输出的txt文件中没有内容。

import urllib
import datetime as dt
from datetime import datetime

import time

linklist = []
with open ("test.txt", 'r', encoding = 'utf=8') as wikitxt :
         #content = wikitxt.read().splitlines()
         for i in wikitxt:
                  linklist.append (i)

output = open('Wikipedia_content.txt', 'w', encoding='utf-8')

startTime = time.time()
endTime = time.time()
runTime = endTime - startTime
print("Runtime is %3f seconds" % runTime)

这是我使用的 txt 文件https://pastebin.com/Y4bwsHGB，这是我需要使用的文本文件：https://pastebin.com/SXDAu8jV。

提前致谢。

解决方案

您可以使用以下函数打开文本文件并将所有链接存储在列表中：

with open('links.txt') as f:
    content = f.read().splitlines()

该变量content是一个列表，其中每个元素都包含与 URL 关联的字符串。这仅在您links.txt逐行排列 URL 时才有效，即：

www.google.co.in
www.wikipedia.co.in
www.youtube.co.in

一旦你得到这个列表，你就可以用一个简单的 for 循环遍历它，然后做你想做的事。

如果您想要更详细的答案，我建议发布链接的示例文本文件。

编辑 ：

这可行，但它将整个数据转储到文件中。数据格式不正确。这是你需要的吗？

from urllib.request import urlopen
with open('links.txt') as f:
    content = f.read().splitlines()

with open('Wikipedia_content.txt', 'w') as output_file:
for link in content :
    output_file.write(link)
    output_file.write((urlopen(link).read()))
