使用BeautifulSoup循环爬取NFL多页面时遇AttributeError问题求助

我正在学习用Python BeautifulSoup做基础网页爬取，目标是遍历32个NFL球队页面，获取各队2022年的胜负数据。但代码执行到DataFrame第二次迭代时，出现了AttributeError错误。手动测试单个球队时代码能正常运行，想知道循环中使用req和soup时是不是漏了步骤，期望代码能遍历Excel文件构建的每个球队URL，输出各队每场的胜负结果。

原代码 #

import requests 
from urllib.request import Request, urlopen
from bs4 import BeautifulSoup as soup

import pandas as pd

year = '2022'
df = pd.read_excel('NFL_Team_Names.xlsx')

for i, j in df.iterrows():
    url_insert = j[0].replace(' ', '-')  
    url = 'https://champsorchumps.us/team/nfl/' + url_insert + '/' + year
    print(url)
    req = Request(url , headers={'User-Agent': 'Mozilla/5.0'})

    webpage = urlopen(req).read()
    soup = soup(webpage, "html.parser")

    games = 18
    
    for x in range(1, games):

        insert = 'game_' + str(x)

        wl_count = 0
        row = soup.find('tr', id=''+insert)
        for elements in row.find_all('td'):   
            if(wl_count == 3):
                win_lose = elements.get_text().strip()
                print(j[0] + " " + insert + " " + win_lose[0])
            wl_count = wl_count + 1

错误信息 #

raise AttributeError(
AttributeError: ResultSet object has no attribute 'find'. You're probably treating a list of elements like a single element. Did you call find_all() when you meant to call find()?

问题核心是变量名冲突：你将BeautifulSoup类导入时命名为soup，但在循环里又把解析后的页面对象赋值给了同名变量soup。第一次循环时，soup还是类实例能正常工作；第二次循环时，soup已经变成了解析后的ResultSet对象，再调用soup(webpage, "html.parser")就会触发错误——此时soup已经不是原本的BeautifulSoup类了。

同时，部分球队可能不足18场比赛，row找不到时直接调用find_all()也会报错，需要增加判断逻辑。

修改后的代码：

import requests 
from urllib.request import Request, urlopen
from bs4 import BeautifulSoup as soup

import pandas as pd

year = '2022'
df = pd.read_excel('NFL_Team_Names.xlsx')

for i, j in df.iterrows():
    url_insert = j[0].replace(' ', '-')  
    url = 'https://champsorchumps.us/team/nfl/' + url_insert + '/' + year
    print(url)
    req = Request(url , headers={'User-Agent': 'Mozilla/5.0'})

    webpage = urlopen(req).read()
    # 更换解析后页面的变量名，避免和导入的soup类冲突
    page_soup = soup(webpage, "html.parser")

    games = 18
    
    for x in range(1, games):
        insert = 'game_' + str(x)
        wl_count = 0
        # 使用新的变量名查找元素
        row = page_soup.find('tr', id=insert)
        # 找不到对应场次的行就跳过，避免报错
        if not row:
            continue
        for elements in row.find_all('td'):   
            if wl_count == 3:
                win_lose = elements.get_text().strip()
                print(f"{j[0]} {insert} {win_lose[0]}")
            wl_count += 1
