ElementTree SyntaxError: expected path separator ([)

This may be side-stepping the question, but you could just try copying-and-
pasting the version of ElementTree from Python 2.7, renaming it to avoid
conflicting with the standard library, and importing and using that.

However, since ElementTree isn’t meant to be used as a standalone file, what
you need to do is navigate to

C:Python27Libxml

and copy the entire

etree

folder and import ElementTree by doing

import etree.ElementTree

inside your script.

To avoid accidentally importing or using the version of ElementTree from
Python 2.6, you should probably rename the

etree

folder, its contents,
delete the

.pyc

files, and fix the imports inside the file to reference the
Python 2.7 version.
