我正在學習如何通過 Python 使用 BeautifulSoup 庫，為了練習，我嘗試從這個維基百科頁面中刪除流派標題： https ://en.wikipedia.org/wiki/List_of_jazz_genres我已經能夠在我的代碼中做到這一點：from bs4 import BeautifulSouphtml = open("wiki-jazz.html", encoding="utf=8")soup = BeautifulSoup(html, "html.parser")table = soup.find_all("table")[1]td = table.find_all("td")print(td)table[1] 包含我想要訪問的數據。更具體地說，我真的只需要位于此標題屬性中的數據：</td>, <td><a href="/wiki/West_Coast_jazz" title="West Coast jazz">West Coast jazz</a>我一直在絞盡腦汁地思考如何提取這些信息。我已經看過這里的其他帖子，但無法完全理解。謝謝。

要打印表格的第一列，您可以迭代行 ( <tr>)，然后獲取行 ( <td>) 的所有單元格。每行的第一個單元格是您的爵士樂流派：
import requests
from bs4 import BeautifulSoup
url = 'https://en.wikipedia.org/wiki/List_of_jazz_genres'
soup = BeautifulSoup(requests.get(url).content, "html.parser")
table = soup.find_all("table")[1]
for row in table.find_all('tr')[1:]: # <-- [1:] because we don't want the header
cells = [td.get_text(strip=True) for td in row.find_all('td')]
print(cells[0])
