如何在Python中解析div中的HTML表而不是表

Question

我正在尝试从本网站解析表。我从Username列开始，在堆栈溢出的帮助下，我能够使用以下代码获得Username的内容：

with open("Top 50 TikTok users sorted by Followers - Socialblade TikTok Stats _ TikTok Statistics.html", "r", encoding="utf-8") as file:
    soup = BeautifulSoup(str(file.readlines()), "html.parser")

tiktok = []
for tag in soup.select("div div:nth-of-type(n+5) > div > a"):
    tiktok.append(tag.text)

这给了我

['addison rae',
 'Bella Poarch',
 'Zach King',
 'TikTok',
 'Spencer X',
 'Will Smith',
 'Loren Gray',
 'dixie',
 'Michael Le',
 'Jason Derulo',
 'Riyaz',
.
.
.

我的最终目标是用[Rank, Grade, Username, Uploads, Followers, Following, Likes]填充整个表

我读过几篇关于Parsing HTML Tables in Python with BeautifulSoup and pandas的文章，但没有起作用，因为在源代码中没有将它定义为表。在Python中将其作为表的替代方法有哪些？

Answer 1

您可以使用以下代码将HTML从一个文件加载到另一个文件，然后将表解析为dataframe：

import pandas as pd
from bs4 import BeautifulSoup

soup = BeautifulSoup(open("page.html", "r").read(), "html.parser")

data = []
for div in soup.select('div[style*="fafafa"], div[style*="f8f8f8"]'):
    data.append(
        [
            d.get_text(strip=True)
            for d in div.find_all("div", recursive=False)[:8]
        ]
    )


df = pd.DataFrame(
    data,
    columns=[
        "Rank",
        "Grade",
        "Username",
        "Uploads",
        "Followers",
        "Following",
        "Likes",
        "Interactions",
    ],
)
print(df)
df.to_csv("data.csv", index=False)
