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.

from lxml import etree 安装

如果你使用的是Anaconda环境，可以使用以下命令：
