<built-in function =“”__ import __ =“”>返回错误集

Question

当我尝试按docs.python.org中提到的import ElementTree时，我收到以下错误消息。

我在这里做错了什么？

AttributeError: module 'copy' has no attribute 'deepcopy'

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "C:/Pycharm/PycharmProjects/untitled/temp.py", line 1, in <module>
    from xml.etree.ElementTree import ElementTree
  File "C:\Users\chilukuri\AppData\Local\Programs\Python\Python36-32\lib\xml\etree\ElementTree.py", line 1654, in <module>
    from _elementtree import *
SystemError: <built-in function __import__> returned a result with an error set

从这一行开始

File "C:\Users\chilukuri\AppData\Local\Programs\Python\Python36-32\lib\xml\etree\ElementTree.py", line 1654, in <module>
        from _elementtree import

据我所知，从_elementtree

导入*失败了

我试着在整个Python36-32目录中搜索这个* _elementtree *，但是找不到它，是不是这个原因？
