爬取课程表时出现'NoneType' object has no attribute 'find_all'错误求助

错误原因 #

你在查找表格时写错了HTML标签名：代码里用了'tabele'，但目标HTML中的表格标签是<table>，导致soup.find()返回None，后续调用table.find_all()触发了AttributeError。

修复后的代码 #

将标签名修正为'table'即可，完整代码如下：

import requests
from bs4 import BeautifulSoup
import pandas as pd

with open ('o24.html','r') as f:
    content = f.read()
    soup = BeautifulSoup(content, 'lxml')
    # 修正标签名：tabele → table
    table = soup.find('table', class_='tabela')
    header =[]
    rows = []
    for i, row in enumerate(table.find_all('tr')):
        if i == 0:
            header = [el.text.strip() for el in row.find_all('th')]
        else:
            rows.append([el.text.strip() for el in row.find_all('td')])
    print(header)
    for row in rows:
        print(row)

额外建议 #

为避免类似NoneType错误，建议添加存在性检查，防止查找失败后程序崩溃：

table = soup.find('table', class_='tabela')
if table:
    # 后续处理逻辑
    header =[]
    rows = []
    for i, row in enumerate(table.find_all('tr')):
        if i == 0:
            header = [el.text.strip() for el in row.find_all('th')]
        else:
            rows.append([el.text.strip() for el in row.find_all('td')])
    print(header)
    for row in rows:
        print(row)
else:
    print("未找到目标表格，请检查标签名或class是否正确")
