python - ResultSet 对象没有属性 'find_all'

Question

当我抓取一个网页时，我总是遇到一个问题。

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

谁能告诉我如何解决这个问题？我的代码如下:

import requests  
r = requests.get('https://www.example.com')
from bs4 import BeautifulSoup  
soup = BeautifulSoup(r.text, 'html.parser')  
results = soup.find_all('div', attrs={'class':'product-item item-template-0 alternative'})
records = []  
for result in results:  
    name = results.find('div', attrs={'class':'name'}).text 
    price = results.find('div', attrs={'class':'price'}).text[13:-11]
    records.append((name, price,))

我想问一个封闭的问题。如果我想废弃多个页面。如下所示的模式，我使用如下代码，但仍然只废弃第一页，你能解决这个问题吗？

import requests  
for i in range(100):   
    url = "https://www.example.com/a/a_{}.format(i)"
    r = requests.get(url)
from bs4 import BeautifulSoup  
soup = BeautifulSoup(r.text, 'html.parser')  
results = soup.find_all('div', attrs={'class':'product-item item-template-0 alternative'})

Answer 1

试试这个。您将结果与结果混淆了:

import requests  
r = requests.get('https://www.example.com')
from bs4 import BeautifulSoup  
soup = BeautifulSoup(r.text, 'html.parser')  
results = soup.find_all('div', attrs={'class':'product-item item-template-0 alternative'})
records = []  
for result in results:  
    name = result.find('div', attrs={'class':'name'}).text # result not results
    price = result.find('div', attrs={'class':'price'}).text[13:-11]
    records.append((name, price,))
