HTML表格到适当的excel表格Python

我是Python新手，正在努力将web抓取数据打印到漂亮的excel表中。 下面是一个表，我正试图在Python中进行刮取和复制：

以下是HTML页面的外观：

</div>
    <section id="first" style="display:none" aria-label="Power situation graph section">
        <div class="gridModule-2up">
            <div class="prognos_controls hidden" data-proggraph="1">
                Show data for:
                <button value="1" onclick="this.blur();" type="button" class="btn  btn--secondary prognosdaybutton"><span class="fa fa-clock-o" aria-hidden="true"></span> Yesterday</button>
                <button value="2" onclick="this.blur();" type="button" class="btn  btn--tertiary prognosdaybutton"><span class="fa fa-clock-o" aria-hidden="true"></span> Today</button>

            </div>

这是我的输出与此代码的外观：

如何在此基础上创建正常数据框，然后将其导出到Excel

我将非常感谢任何帮助。

试着在这里和熊猫一起去。它在引擎盖下使用beautifulsoup。我无法在你的URL上测试它，因为你还没有提供

import pandas as pd

url = 'myURLlink'
df = pd.read_html(url)[1]

df.to_csv('file.csv', index=False)
print (df.to_string())

问题是因为转义字符

from bs4 import BeautifulSoup

with open("sample.html", "r") as f:

    contents = f.read()
    soup = BeautifulSoup(contents, 'lxml')
    extract = soup.find("table")

    # added strip() to remove leading and trailing characters
    table = [[item.text.strip() for item in row_data.select("th,td")]
                    for row_data in extract.select("tr")]

    for item in table:
        print(' '.join(item))

您可以从代码片段中删除无用的导入（

，

lxml.html

，

请求

，

pandas

）。以及没有提供价值的评论行。谢谢库纳尔！这很有帮助。有可能根据这个结果创建一个数据帧吗？Katya，有可能。只需将列表转换为dataframe:-df=pd.dataframe（表）和yes，而不是df.to_csv（“demo.csv”，index=False），就可以从代码段中删除无用的导入（

df.to_csv（'file.csv'，encoding='utf-8-sig'，index=False）
