代码是否可以在网络抓取中跳过一次迭代？ IndexError：弹出索引超出范围-PHP中文网问答

所以我有一个代码，它从 14 页（到目前为止）中删除矿物的名称+价格并将其保存到 .txt 文件中。我首先尝试仅使用 Page1，然后我想添加更多页面以获取更多数据。但随后代码抓取了一些它不应该抓取的东西——随机名称/字符串。我没想到它会抢到那个，但它确实抢到了，并且给这个分配了错误的价格！它发生在具有这种“意外名称”的矿物之后，然后列表中的整个其余部分都有错误的价格。见下图：

因此，由于该字符串与其他字符串不同，因此进一步的代码无法拆分它并给出错误：

cutted2 = split2.pop(1)
              ^^^^^^^^^^^^^
IndexError: pop index out of range

我试图忽略这些错误并使用不同 Stackoverflow 页面中使用的方法之一：

try:
   cutted2 = split2.pop(1)
except IndexError:
   continue

它确实有效，没有出现错误......但随后它为错误的矿物分配了错误的价格（正如我注意到的）！如何更改代码以忽略这些“奇怪”的名称并继续列表？下面是完整的代码，我记得它停在 URL5 上，并给出了这个弹出索引错误：

编辑：这是下面完全有效的代码，感谢帮助人员！

import requests

    soup = BeautifulSoup(requests.get(f'https://www.fabreminerals.com/search_results.php?LANG=EN&SearchTerms=&submit=Buscar&MineralSpeciment=&Country=&Locality=&PriceRange=&checkbox=enventa&First={URL}', headers=headers).text, "lxml")

    names = [n.getText(strip=True) for n in soup.select("table tr td font>a")]

    prices = [p.getText(strip=True).split("Price:")[-1] for p in soup.select("table tr td font>font")]   
       
    names[:] = [" ".join(n.split()) for n in names if not n.startswith("[") ]
    prices[:] = [p for p in prices if p]

    with open("MineralsList.txt", "a+", encoding='utf-8') as file:
        for name, price in zip(names, prices):
                # print(f"{name}\n{price}")
                # print("-" * 50)
                filename = str(name)+"  "+str(price)+"\n"
                split1 = filename.split(' / ')          
                cutted1 = split1.pop(0)
                split2 = cutted1.split(": ")
                cutted2 = split2.pop(1)
                try:
                    two_prices = cutted2+"  "+split1.pop(0)+"\n"
                except IndexError:
                    two_prices = cutted2+"\n"
                file.write(two_prices)

但是经过一些更改后，它会因新错误而停止 - 它无法通过给定属性找到字符串，因此出现错误“IndexError：从空列表中弹出”...甚至 soup.select("table tr td font>font" ) 提供了帮助，就像它在“名称”中所做的那样
