Hi everyone.

This question is in continuation to my previous question, in which I asked about passing around an ElementTree.

I need to read the XML files only and to solve this, I decided to create a global ElementTree and then parse it wherever required.

My question is:

Is this an acceptable practice? I heard global variables are bad. If I don't make it global, I was suggested to make a class. But do I really need to create a class? What benefits would I have from that approach. Note that I would be handling only one ElementTree instance per run, the operations are read-only. If I don't use a class, how and where do I declare that ElementTree so that it available globally? (Note that I would be importing this module)

Please answer this question in the respect that I am a beginner to development, and at this stage I can't figure out whether to use a class or just go with the functional style programming approach.
