https://xxx.ilovefishc.com/album/202003/21/201545jk3ksp5z8hyaj3yy.png
我这里python 3.8.2 64位，没有要求改。
另外我查了下lxml官网api手册，没说改名，还是这个方式导入：https://lxml.de/api.html

用这个查的
https://github.com/python/cpython/tree/3.8/Lib/

XML tree and elements
XML is an inherently hierarchical data format, and the most natural way to represent it is with a tree. ET has two classes for this purpose - ElementTree represents the whole XML document as a tree, and Element represents a single node in this tree. Interactions with the whole document (reading and writing to/from files) are usually done on the ElementTree level. Interactions with a single XML element and its sub-elements are done on the Element level.

我只能用这个库才能跑起来
from xml import etree

查了一下，xml是python自带的库。
我用的lxml是第三方库，需要单独安装。
