My first project : help me

Recently we are doing a project in our university.
IT subject - OOP (object oriented programming module)

Last semester we dealt with the same project using python.
We are continuing it because I (we) want to make it commercial. It has potential.

I'm a newbie into oop - I need your help guys.
Last semester we had,

• basic calculations(the fundamental of the software)
• Simple UI (streamlit - fully made with AI)
• Some cool features(just ideology)

And it was totally enough for a 30 marks final assessment for a 1 credit computational thinking module.

But now we have to continue the same project and we are facing these issues.

1. Lecturer says we need to convert code into oop - objects ,classes , blah blah
2. Also need to add some calculations - its okey i can handle it
3. We have no clear architecture - this causes many problems like now we cannot filter our     business logic from our UI that is made by AI.
4. AI assistant

This is my plan to escape from the matrix >>>
01. OOP Restructuring

2. File handling

3. Correlation module

4. Interpretation engine

5. API wrapper

6. Saas layer

Currently i m learning basics of oop - (python)

Then my next idea is to deal with software architecture. That will avoid hundreds of problems that will be caused in future.

Little chat with chatgpt convinced me - I should go with a layered structure.

What is your idea on this workflow, frameworks, architecture?
(Corrections will be kindly accepted, I want to learn in the ryt way.)
