我正在设计一个Python代码，使用Selify库来收集e-Dreams平台上可用的酒店数据。代码的目的是收集一些数据，如标题和当前价格，将它们存储在列表中，然后创建一个数据集。问题是，代码会运行，但在某些执行中，价格数据被正确存储，而其他时候则不正确。这是通过最后的指纹识别出来的。你知道为什么会这样吗？有可能有防刮擦的措施

page=BeautifulSoup(driver.page_source,'html.parser')
hotel_name=[]
price_now=[]

for i in page.findAll('div',attrs={'class':'d20f4628d0'}):    
         title=i.find("div",attrs={'fcab3ed991 a23c043802'})
         if title:

         else: price_now.append('')

df=pd.DataFrame({'Name':hotel_name,
                 'Price':price_now})

driver.quit()

在这里您可以看到价格的类别
Actual price
我已经运行了几次代码，根本没有任何更改，在某些情况下，价格存储在数据集中，而在另一些情况下则不是。其他变量不会发生这种情况，只有价格会发生这种情况。
