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頁面，但這不是問題。）我想要每個括號中的團(tuán)隊名稱（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td 。但是每次嘗試[0]獲取td每一行的第一行都會給我一個“索引超出范圍”錯誤。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)過幾個小時的工作后，我覺得只需更改一個語法即可實現(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

每個括號對應(yīng)一個“面板”，每個面板有兩行，第一行包含比賽表中所有球隊的第一個表。
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：
OCYS
FL Rush
Jacksonville FC
Atlanta United
SSA
Miami Rush Kendall SC
IMG
Tampa Bay United
Weston FC
Chargers SC
South Florida FA
Solar SC
RISE SC

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元素時，它會導(dǎo)致范圍索引錯誤。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)隊名稱。
