抓取HTML表格python bs4

Question

我会从 Transfermarkt 玩家资料页面中的两个 html 表中抓取数据。 这是一个页面示例：https://www.transfermarkt.com/cristiano-ronaldo/profil/spieler/8198

第一个是“事实和数据”表，第二个是“统计”表。我想从搜索页面开始抓取并获取网址。 一旦我从搜索页面的每一页获取了 url，就开始为每个播放器链接抓取统计信息。

如何从该链接中抓取 html 表格的数据？

这是我的完整代码

import requests
from bs4 import BeautifulSoup
import pandas as pd
import time

url_page="https://www.transfermarkt.com/detailsuche/spielerdetail/suche/27403221"

response = requests.get(url=url_page,

response.elapsed.seconds
soup = BeautifulSoup(response.content, "html.parser")


for link in soup.find_all('table',class_='items'):
    for link_pag in link.find_all(class_='spielprofil_tooltip'):
        #add page loop
        url_page="https://www.transfermarkt.com"+link_pag.attrs["href"]
        response_pagina = requests.get(url=url_page,
                            headers={'User-Agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_13_4) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/35.0.1916.47 Safari/537.36'})
        soup_pagina = BeautifulSoup(response_pagina.content, "html.parser")
        time.sleep(3)

        for n_player in soup_pagina('h1', itemprop="name"):
            name = n_player.text
        for value_player in soup_pagina('span', class_="waehrung"):
            price = value_player.text

        data_table = soup_pagina.find('table', class_='auflistung')
        for data in data_table.find_all('tbody'):
            rows = data.find_all('tr')
            for row in rows:

                place_of_birth = row.find('td', [2]).text
                age = row.find('td', [3]).text
                height = row.find('td', [4]).text
                citizenship = row.find('td', [5]).text

您可以使用这个示例如何从播放器页面获取数据并从中创建一个 DataFrame（当然，它需要您的修改）：

import requests
import pandas as pd
from bs4 import BeautifulSoup


def get_player(url):
    headers = {
        "User-Agent": "Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:87.0) Gecko/20100101 Firefox/87.0"
    }
    soup = BeautifulSoup(
        requests.get(url, headers=headers).content, "html.parser"
    )

    data = {}
    # data:
    for th in soup.select(".auflistung th"):
        data[th.text.split(":")[0].strip()] = th.find_next("td").get_text(
            strip=True
        )

    # stats:
    for tr in soup.select(".items tr.odd, .items tr.even"):
        row = [td.get_text(strip=True) for td in tr.select("td")[1:]]
        data[row[0]] = row[1:]

    return pd.DataFrame([data])


df1 = get_player(
    "https://www.transfermarkt.com/cristiano-ronaldo/profil/spieler/8198"
)
df2 = get_player(
    "https://www.transfermarkt.com/wojciech-szczesny/profil/spieler/44058"
)

df = pd.concat([df1, df2])

print(df)
df.to_csv("data.csv", index=False)

打印：
