我正在嘗試將此物件的價格轉換為變數并將其列印出來/放入 CSV 中。
這是我要決議的 html 部分：
<span class="price" data-js-product-price="">
<span>$429.00 USD</span>
</span>
這是我的 python 代碼（對不起，我對 python 有點陌生，我一直在嘗試解決這個問題，如果代碼有點混亂，很抱歉）
from bs4 import BeautifulSoup
url_to_scrape = "https://www.backfireboards.com/?gclid=CjwKCAjwjtOTBhAvEiwASG4bCGHPgmV4XjyqAIFrW0Lr0IiW0AvfTiC7sZ4E-HtM_qJ9k4ahAu2CHxoCH5YQAvD_BwE"
request_page = urlopen(url_to_scrape)
page_html = request_page.read()
request_page.close()
html_soup = BeautifulSoup(page_html, 'html.parser')
board_prices = html_soup.find_all('span', class_='price')
print("num of prices: " str(len(board_prices)))
file_name = 'product.csv'
f = open(file_name,'w')
headers = 'Title, Price \n'
f.write(headers)
i = 1
for price in board_prices:
currPrice = price.span.text
print(i)
i = i 1
print(price)
print(currPrice)
f.close()
這是我得到的錯誤：
Traceback (most recent call last):
File "/Users/isaiah/PycharmProjects/Web_scrape/main.py", line 26, in <module>
currPrice = price.span.text
AttributeError: 'NoneType' object has no attribute 'text'
我知道這不是文本物件，但是當我在沒有 .text 的情況下列印它時，它會吐出：
1
<span class="price" data-js-popup-cart-subtotal=""></span>
None
2
<span class="price" data-js-product-price=""><span></span></span>
<span></span>
3
<span class="price" data-js-product-price=""><span></span></span>
<span></span>
4
<span class="price"><span></span></span>
<span></span>
5
<span class="price" data-js-product-price=""><span></span></span>
<span></span>
6
<span class="price" data-js-product-price=""><span></span></span>
<span></span>
我不知道為什么 429 美元在物件中消失了，我對網路抓取等有點陌生。有什么很簡單的我也很無知嗎？
另外，據我所知，該網站實際上在此頁面上列出了我從中提取的 8 個價格，但 board_prices 物件的大小僅為 6？有人也可以向我解釋一下嗎？
