Python beautifulsoupselect方法返回回溯

我仍然在学习beautifulsoup模块，我在用python自动化枯燥的东西这本书中对此进行了回复我尝试了回复get amazon price脚本，但我得到了.select方法的回溯 错误“TypeError:”非类型“对象不可调用” 我找不到太多关于这个错误的信息，它被这个错误搞得一团糟

help(soup.Select)

与之相比：

help(soup.select)

Out[2]:
Help on method select in module bs4.element:

select(selector, namespaces=None, limit=None, **kwargs) method of bs4.BeautifulSoup instance
    Perform a CSS selection operation on the current element.

    This uses the SoupSieve library.

    :param selector: A string containing a CSS selector.

    :param namespaces: A dictionary mapping namespace prefixes
    used in the CSS selector to namespace URIs. By default,
    Beautiful Soup will use the prefixes it encountered while
    parsing the document.

    :param limit: After finding this number of results, stop looking.

    :param kwargs: Any extra arguments you'd like to pass in to
    soupsieve.select().

话虽如此，看起来页面结构实际上与您试图获取的页面结构不同，缺少标记

买新的 $16.83 因此，这应该是可行的：

p=汤。选择“buyNewSection>h5>div>div.a-column.a-span8.a-text-right.a-span-last>div.inlineBlock-display>span.a-size-medium.a-color-price.offer price.a-text-normal” abc=p[0].text.strip abc 出[2]： '$16.83'

另外，您可以考虑使用更细粒度的方法，让您更好地调试代码。例如：

buySection=soup.find'div'，attrs={'id'：'buyNewSection'} buySpan=buySection.find'span'，attrs={'class'：'a-size-medium a-color-price offer price a-text-normal'} 打印buyScan 出[1]： '$16.83'

---

这意味着您选择的元素不再存在
