推荐答案

下面的代码就足够了。您无需在开始时打开文件。如果提供正确的路径， ET.parse 会为您完成。

The following code is enough. You don't need to open the file at beginning. ET.parse will do it for you if you provide the correct path.

在您的代码中，导入库作为ET，然后通过打开文件重新分配相同的变量。因此， ET.parse（）是指您的文件对象，而不是 elementtree 库。

In your code you import the library as ET and then reassign the same variable by opening the file. So ET.parse() referes to your file object not to your elementtree library.

import xml.etree.ElementTree as ET

tree= ET.parse('note.xml')
root= tree.getroot()
print(root.tag) # to print root
