我尝试用 Python 或 bs4 中的 BeautifulSoup 解析以下 HTML 代码：
<div class="product w-100" data-pid="BBOMNLV1-36183" data-sid="BBOMNLWB">

我正在尝试通过查找具有“tile-image ls-is-cached lazyloaded”类的 img 标签来检索鞋子的 pciture，然后我尝试检索 data-src 属性以获取照片的链接。
这是我的 bs4 代码，它似乎不起作用：
from bs4 import BeautifulSoup
def queryNewBalance(uri):
r = requests.get('https://www.newbalance.com/men/shoes/basketball/?prefn1=color&prefv1=Black%7CBlue&srule=null')
soup = BeautifulSoup(r.content, 'html.parser')
result = soup.find_all('div', class_='product w-100')
for res in result:
print("*******************************")
print(res.find('img', class_='tile-image ls-is-cached lazyloaded')['href]) #Picture
print("*******************************")
print(f"\nFound total shoes: {len(result)}")
如何修复我的代码以检索图片链接？

hmmm.. 你正在做一个
import bs4我认为它应该是from bs4 import BeautifulSoup或者你可能只是没有在这里粘贴它 -
