In python 2 documentation 19.7.1.6
(https://docs.python.org/2/library/xml.etree.elementtree.html#parsing-xml-with-namespaces)
a second argument (ns) is passed to find and findall.

However 19.7.3.2
(https://docs.python.org/2/library/xml.etree.elementtree.html#xml.etree.ElementTree.Element.find)
only specifies the single match argument.

If we compare the python 3 documentation the namespaces argument is included in the find method. (https://docs.python.org/3/library/xml.etree.elementtree.html#xml.etree.ElementTree.Element.find)

Maybe the tutorial was created for python 3 version? I assume the function arguments are automatically generated, but I have not tested or tried these functions in python 2. I just stumbled on the docs while working with python 3.

Python 2.7 is no longer supported.
