我正在尝试使用BeautifulSoup4抓取Craigslist。除价格外，所有数据都显示正确。我似乎找不到合适的标签来循环定价，而不是显示每个帖子的相同价格。
import requests
from bs4 import BeautifulSoup
source = requests.get('https://washingtondc.craigslist.org/search/nva/sss?query=5%20hp%20boat%20motor&sort=rel').text
soup = BeautifulSoup(source, 'lxml')
for summary in soup.find_all('p', class_='result-info'):
pricing = soup.find('span', class_='result-price')
price = pricing
title = summary.a.text
url = summary.a['href']
print(title + 'n' + price.text + 'n' + url + 'n')
左：来自Craigslist的HTML代码，被注释掉是无关的(在我看来(代码。我希望定价不重复相同的数字。右图：代码的Sublime SS。
通过终端运行的代码段。每个帖子的价格都是一样的。
谢谢
您的脚本几乎是正确的。您需要将价格的汤对象更改为summary
