美化对汤有效，但对汤无效1=汤。全部查找

Question

MyAlphaSoup = BeautifulSoup(website_to_crawl.text, 'html.parser')

MyAlphaSoup.prettify()

MyAlphaAlphaSoup = MyAlphaSoup.find_all("div", {"class": "lister-item featurefilm"})

MyAlphaAlphaSoup.prettify()

我在第四行出错了

raise AttributeError( AttributeError: ResultSet object has no attribute 'prettify'. You're probably treating a list of elements like a single element. Did you call find_all() when you meant to call find()?

难道汤不都只是把汤缩小到一个较小的子集吗？所以类型没有改变

Answer 1

这是因为函数find_all返回一个列表。因此，如果指定列表的元素或循环，您应该能够做到这一点：

my_alpha_soup = BeautifulSoup(website_to_crawl.text, 'html.parser')

my_alpha_soup.prettify()

list_of_elements = my_alpha_soup.find_all("div", {"class": "lister-item featurefilm"})

for element in list_of_elements:
    print(element.prettify())

此外，还有一个惯例，即只对类使用首字母大写
