如何在 bs4 [ python 3 ] 中的另一个标签内没有 class 或 id 的情况下从标签中抓取 url

Question

我想从 ( h2 class="" > a href="" : )

中获取所有 url

此代码：

import requests
from bs4 import BeautifulSoup

header = {"User-Agent":"Mozilla/5.0 (Windows NT 6.1; WOW64; rv:77.0) Gecko/20190101 Firefox/77.0"}

Purl = 'https://www.tunisianet.com.tn/301-pc-portable-tunisie'

req = requests.get(Purl, headers=header)
soup = BeautifulSoup(req.content, 'lxml')

ProductUrl = []



#find title of product
showName = soup.select('h2',{'class':'h3 product-title'})


#find link of product
for i in showName:
    ProductUrl.append(str(i.find('a')))

print(ProductUrl)
for i in ProductUrl:
    print(i[i.find("href"):])

我该如何解决？

例如：

Answer 1

这是所需的输出：

代码

import requests
from bs4 import BeautifulSoup

header = {"User-Agent":"Mozilla/5.0 (Windows NT 6.1; WOW64; rv:77.0) Gecko/20190101 Firefox/77.0"}

Purl = 'https://www.tunisianet.com.tn/301-pc-portable-tunisie'

req = requests.get(Purl, headers=header)
soup = BeautifulSoup(req.content, 'lxml')

ProductUrl = []



#find title of product
showName = soup.select('h2.h3.product-title a')


#find link of product
for i in showName:
    ProductUrl.append(i.get('href'))

#print(ProductUrl)
for i in ProductUrl:
    print(i)

输出
