I have no idea how to make tree an instance.
Reading the documentation,
https://docs.python.org/2/library/xml.etree.elementtree.html,
it shows as an example:

import xml.etree.ElementTree as ET
tree = ET.parse('country_data.xml')

which is exactly what the program looks like and what my small python script 
does without an error.
