soup.find(id = "productTitle")這是返回，因為它無法找到.確保搜索正確的元素。Noneid = "producTitle"
對于語句，我建議始終編寫if條件以避免和處理此類錯誤。find
title = soup.find(id = "productTitle")
if title:
title = title.get_text()
else:
title = "default_title"
price = soup.find(id = "priceblock_ourprice").get_text()
您可以使用 執行相同的操作。price

好吧，我在這里測試了你的代碼，它工作正常。但是，當您嘗試在短時間內訪問同一鏈接時，亞馬遜會為您提供503代碼...

當您嘗試從值為 None 的對象中提取數據時，您會收到該錯誤。如果您在第 18 行看到這一點，則表示您不匹配任何內容并返回了 None。soup.find(id = "productTitle")
您需要將處理分解為多個步驟。在訪問返回值之前，請先檢查它。所以。。。
title_info = soup.find(id = "productTitle")
if title_info:
title = title_info.text
else:
'handle the situation'

也試試這個代碼
title = soup.find(id="productTitle")
if title:
title = title.get_text()
else:
title = "default_title"
price = soup.find(id="priceblock_ourprice")
if price:
price = price
else:
price = "default_title"
# converted_price = price[0:8]
convert = str(price)
con = convert[-18:-11]
print(con)
print(title)
嘗試使用其他 IDE
