我试图获得给定尺寸的产品价格，因为它们每天都在波动。我能够让我的代码在使用“类”的网站上工作，但我无法让它与 div 和 span 类一起工作。

import pandas as pd                                                                        

driver = webdriver.Chrome("/Users/donlento7/chromedriver")

driver.get('https://www.flightclub.com/supreme-x-dunk-sb-low-varsity-red-varsity-red-white-black-152127?size=9.5')

content = driver.page_source                                                               
soup = BeautifulSoup(content, "lxml")                                                      
for a in soup.findAll('div',href=True, attrs={'class':'product-essential row-fluid product-type-configurable'}):
    name=a.find('div', attrs={'class':'mb-padding'})
    price=a.find('span', attrs={'class':'price'})                                      
    products.append(name.text)
    prices.append(price.text)

df = pd.DataFrame({'Product Name':products,'Price':prices})                                
#df.to_csv('products.csv', index=False, encoding='utf-8')                                  
print(df)

输出：

Empty DataFrame
Columns: [Product Name, Price]
Index: []

由于该行，您将获得 EMPTY 列表。

for a in soup.findAll('div',href=True, attrs={'class':'product-essential row-fluid product-type-configurable'}):

标签中没有href属性。div

将此更改为：

for a in soup.findAll('div',attrs={'class':'product-essential row-fluid product-type-configurable'}):
