soup = BeautifulSoup(html,"html5lib")#use any parser you want.

for td in soup.find_all("td"):
    print(td)# This outputs the not sorted <td> tags

非常感谢你！非常感谢您的帮助。

这应该可以完成这项工作，并为您提供包含

标记的已排序

td

标记的列表

从bs4导入美化组
html=“”
'''
soup=BeautifulSoup（html，'html.parser'）
#函数获取一个标记，找到它的子标记
#然后，它会找到其中的文本，然后将其拆分以获得数字
#然后将其作为int返回给排序函数
def分类汤（项目）：
item=列表（item.children）[0]。文本
数据=项目。拆分（“”）
返回int（数据[1]）
out=soup.findAll（'td'））
out=已分拣（out，key=lambda元素：分拣（元素））
打印（输出）

Hello@Aasim，太棒了！谢谢！我想我应该用

汤。找到所有的反正它们都一样，我想只是在版本上。谢谢！
