For 循环每个链接打印 3 个 -Python/BeautifulSoup

Question

我有一个简单的 for 循环，它运行但打印每个链接 3 次。为什么？（页面共有 3 个“事件”）

我试图从中抓取的网站 = https://www.aacr.org/get-involved/events/

这是代码->

import requests

from bs4 import BeautifulSoup

import pandas as pd

productlinks = []

url='https://www.aacr.org/get-involved/events/'

r=requests.get(url)

soup=BeautifulSoup(r.content,'html.parser')

productlist=soup.find_all('article',class_='event')

for item in productlist:

    for link in item.find_all('a',href=True):

        productlinks.append(link['href'])

print(productlinks)

Any insights on how i can make it run 1 per link

Answer 1

将最后一个 for 循环更改为：for item in productlist:     productlinks.append(item.a['href'])
