No, my question is even dumber than that, I'm afraid. I mostly follow what you wrote in that link, but I'm not asking how to make a new python function. I'm asking the following newb question: you wrote, for example, obj.inventory_item(n) as a usable python function. Clearly that function does not exist yet on my computer. What do I need to place on my computer, and where do I place it, before I can actually use that specific function in the .py code for a spell? I'm about to create a github account, then will let you know.
