readAndChangeXML.py and Python error?

[AznNoProblem]

Hello. I'm new to using a mac and Python. My first issue was wtf is python, I google'd and quickly solved that. Opened terminal, changed directories to where my pokemon file was, and then i entered 'python readAndChangeXML.py' in the terminal and there's an issue that I'm not too sure how to solve..? If anyone could help, that'd be great, otherwise i'll just theorycraft some more x.x
