I mean the data and the functions that are used to create an object. As the definition above states, objects are collections of data and the functions that operate on the data. Another name for a function inside an object is "operation", and as you'll discover the most common name of all is "method" Any time you see a word in italics in my tutor it means I'm introducing a new technical term. Thus attributes and operations being italicised tells you that these are jargon terms for the data and functions just mentioned. You have already met objects back in the Raw Materials topic and also in strings and files. (Strings and Files are predefined objects in Python) . The OOP topic tells you how to create your own object types, or classes.
