[Tutor] OOPs and general Python questions.

Everyone,

Thank you for the responses. The Chat.gpt question was more of interest sake as the way the company was promoting the capability. 

The explanations of the superclass question is a bit clearer.

Sean,

What is a super class is beyond the scope of this forum but we could discuss what a superclass is compared to a subclass.

Loosely, you start with a class and decide you like what you see and would like a version with a few changes. You make a new class where you specify what class it is based on. The new class is a subclass of the older one and the older one is now a superclass of the new one. It can be that simple.

Realistically, all classes exist in a hierarchy leading back to a top-level you may not be aware of. Classes can have multiple inheritance. When you want to invoke some action from a superclass it can be as simple as calling superclass() but can also be &$%*@.

Does Python care about order. Yep. Oh, and sometimes nope.

More seriously, unlike some other languages that look ahead before evaluating in some context, Python generally expects things to refer to previously identified objects or functions or whatever. It can be more complex and interesting.

A case where order can really matter is when a class declares multiple other classes it inherits from as the search for things it uses (like members in superclasses with the same names, can be a bit hard to explain.

As to your last question, code can be modified in many ways as it runs. Python is generally interpreted. The question is too general. What specifically do you want to know if it can be modified and in what ways. Some people use fairly direct methods and some use some rather arcane ones.

Just as an example, if you had a function declared and used and later decided you want to wrap that function in another that adds some functionality by doing something before and/or after the function is called and then return a possibly modified result, you can trivially do it using something like a decorator that stores the result back into the same name. Other things may be hard to achieve and some may not be possible within a session such as when measures have been taken to stop you from accessing something directly. 

Of course, none of us here is currently an AI so our answers ...
