For循环每个链接打印3个Python/BeautifulSoup

Question

我有一个简单的for循环， 它会运行，但会打印每个链接3次。为什么？（第页共有3个“事件”）

我正试图从中获取的网站=https://www.aacr.org/get-involved/events/

以下是代码->

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'])
