from lxml import etree root=etree.Element('root',intersting='totally') print(etree.tostring(root)) #tostring:把字符串外衣穿上，防止变化

在Python中，`lxml`是一个强大的XML和HTML处理库。当你使用`from lxml import etree`导入`etree`模块后，你可以创建元素树来表示XML文档的结构。在这个例子中：

root = etree.Element('root', interesting='totally')  # 创建一个名为'root'的元素，并设置其属性interesting为'totally'

`Element()`函数用于创建一个新的XML元素，并接受两个参数：元素名称（这里是'resource'）和关键字参数（这里是一个键值对，表示属性名和属性值）。`interesting='totally'`表示设置了元素的`interesting`属性。

然后，`etree.tostring(root)`将这个元素转换成一个字节串（XML格式），这是原始XML元素的字符串表示，包含了元素及其所有属性。`tostring()`的作用就是为XML元素添加结束标签以及必要的转义字符，使其成为可以作为字符串直接输出或保存到文件的内容。

输出结果类似这样的字符串形式（实际输出会包含XML头部信息和换行符）：

<bunch of XML tags>&lt;root interesting="totally"&gt;&lt;/root&gt;</bunch of XML tags>

1. from lxml import etree 2. from lxml import html etree = html.etree

This code imports two modules from the lxml library: "etree" and "html". The first line imports the "etree" module, which is used for processing XML and HTML documents. The second line imports the "html" module, which provides a convenient way of parsing HTML documents.

The third line assigns the "etree" module to the variable "etree", which allows you to use the "etree" methods and functions directly from the "html" module. This is because the "html" module is built on top of the "etree" module, so it includes all of the functionality of the "etree" module.

Overall, this code sets up the environment for working with XML and HTML documents using the lxml library.

翻译这段代码 nb = requests.get(url, headers=head).text from lxml import etree sb = etree.HTML(nb) whh = sb.xpath('//tbody/tr[not(@class)]')

我理解你的意思是，你想要翻译这段代码：nb = requests.get(url, headers=head).text from lxml import etree sb = etree.HTML(nb) whh = sb.xpath('//tbody/tr[not(@class)]')，对吧？翻译如下：nb = requests.get（url，headers = head）.text 从lxml导入etree sb = etree.HTML（nb）whh = sb.xpath（'//tbody / tr [not（@class）]’）
