我有一張噩夢表，沒有為 tr 和 td 標(biāo)簽提供類。示例頁面如下：https ://system.gotsport.com/org_event/events/1271/schedules?age=19&gender=m（您將在下面的代碼中看到我得到了多個(gè)頁面，但這不是問題。）我想要每個(gè)括號中的團(tuán)隊(duì)名稱（沒有其他名稱）。輸出應(yīng)該是：OCYSFL Rush杰克遜維爾 FC亞特蘭大聯(lián)SSA邁阿密拉什 肯德爾 SCIMG坦帕灣聯(lián)等我已經(jīng)能夠獲取指定表中的每個(gè)td 。但是每次嘗試[0]獲取td每一行的第一行都會(huì)給我一個(gè)“索引超出范圍”錯(cuò)誤。代碼是：import requestsimport csv from bs4 import BeautifulSoupbatch_size = 2urls = ['https://system.gotsport.com/org_event/events/1271/schedules?age=19&gender=m', 'https://system.gotsport.com/org_event/events/1271/schedules?age=17&gender=m']# iterate through urlsfor url in urls: response = requests.get(url) soup = BeautifulSoup(response.content, "html.parser")# iterate through leagues and teams leagues = soup.find_all('table', class_='table table-bordered table-hover table-condensed') for league in leagues: row = '' rows = league.find_all('tr') for row in rows: team = row.find_all('td') teamName = team[0].text.strip() print(teamName)經(jīng)過幾個(gè)小時(shí)的工作后，我覺得只需更改一個(gè)語法即可實(shí)現(xiàn)這一目標(biāo)。是的？

您可以使用 CSS 選擇器nth-of-type(n)。它適用于兩個(gè)鏈接：
import requests
from bs4 import BeautifulSoup
url = "https://system.gotsport.com/org_event/events/1271/schedules?age=19&gender=m"
soup = BeautifulSoup(requests.get(url).content, "html.parser")
for tag in soup.select(".small-margin-bottom td:nth-of-type(1)"):
print(tag.text.strip())
輸出：
OCYS
FL Rush
Jacksonville FC
Atlanta United
SSA

每個(gè)括號對應(yīng)一個(gè)“面板”，每個(gè)面板有兩行，第一行包含比賽表中所有球隊(duì)的第一個(gè)表。
def main():
import requests
from bs4 import BeautifulSoup
url = "https://system.gotsport.com/org_event/events/1271/schedules?age=19&gender=m"
response = requests.get(url)
response.raise_for_status()
soup = BeautifulSoup(response.content, "html.parser")
for panel in soup.find_all("div", {"class": "panel-body"}):
for row in panel.find("tbody").find_all("tr"):
print(row.find("td").text.strip())
return 0
if __name__ == "__main__":
import sys
sys.exit(main())
輸出：

我認(rèn)為問題出在表的標(biāo)題上，它包含th元素而不是td元素。當(dāng)您嘗試從空列表中檢索第一個(gè)元素時(shí)，它會(huì)導(dǎo)致范圍索引錯(cuò)誤。嘗試添加長度檢查td：
for row in rows:
team = row.find_all('td')
if(len(team) > 0):
teamName = team[0].text.strip()
print(teamName)
它應(yīng)該打印出團(tuán)隊(duì)名稱。
