嗨，我试图找到一个元素，我很容易找到了第一个元素（soup1_title），但我很难找到下一个元素！我只需要书籍作者，例如第一个我最喜欢的输出是：“由 JG Ballard 和 Martin Amis 撰写”（没有作者）这是问题所在： 这是我需要的领域

这是我写的代码：

import requests
from bs4 import BeautifulSoup
#Search_Text = input('Please Enter Search Query ')
#Search_Text = Search_Text.replace(' ','+')
url = 'https://www.amazon.com/s?k=j+g+ballard+short+stories'
#print(url)
headers = {'User-Agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_10_1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/39.0.2171.95 Safari/537.36'}
r = requests.get(url, headers=headers)
soup = BeautifulSoup(r.text, 'lxml')
soup1_title = soup.select('.a-color-base.a-text-normal')
soup2_title = soup.select('.a-size-base'+'a-link-normal')


for j in soup2_title:
    print(j.string)

链接是：https ://www.amazon.com/s?k=j+g+ballard+short+stories

伙计们，你能帮我用美丽的汤找到上述元素吗？

import requests
from bs4 import BeautifulSoup

params = {
    "k": "j g ballard short stories"
}

headers = {
    'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:74.0) Gecko/20100101 Firefox/74.0'
}


def main(url):
    r = requests.get(url, params=params, headers=headers)
    soup = BeautifulSoup(r.content, 'lxml')
    target = soup.select("div[class$=a-color-secondary]")
    for tar in target:
        if "by" in tar.text:
            print(tar.get_text(strip=True, separator=" "))


main("https://www.amazon.com/s")

输出：
