Question

我尝试了一堆不同的代码组合来尝试从表中获取表数据。简单地使用soup.table不会从页面返回此特定表格，我无法弄清楚原因。

我已经设法通过使用class_:'table assessment-item'按类找到它，但是当我尝试解析单个行或数据时，它会抛出错误。

import requests
from bs4 import BeautifulSoup
page = requests.get("https://www.qut.edu.au/study/unit?unitCode=IFB104")

soup = BeautifulSoup(page.content, 'html.parser')
table = soup.find_all(class_='table assessment-item')
table_data = table.find_all('td')

错误：

Traceback (most recent call last):
File "/Users/study/Desktop/QUT Final/demo.py", line 7, in <module>
table_data = table.find_all('td')
File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/bs4/element.py", line 1807, in __getattr__
"ResultSet object has no attribute '%s'. You're probably treating a list of items like a single item. Did you call find_all() when you meant to call find()?" % key

Answer 1

返回了三个表，其中类为'table assessment-item'。

你只需要迭代它们：

table = soup.find_all(class_='table assessment-item')

table_data = [tbl.find_all('td') for tbl in table]

print table_data
