Interactive Demo
OOP: Class vs Instance Visualizer
OOP: Class vs Instance Visualizer is a free, interactive learning demo from the Intro to Python Fundamentals course on Lykke. It helps you build intuition for Classes and Objects, Instance Attributes and State, Methods and Encapsulation, Special Methods (Dunder Methods). Play with it directly in your browser — it features 4 sliders and 1 button. Click "Instantiate" to create a concrete object in memory. This demo lives in the “Unit 6: Object-Oriented Programming (OOP)” section of the course.
How to use this demo
- Click "Instantiate" to create a concrete object in memory.
- Drag the “Class Attribute: base_size”, “Attribute: color_hue”, “Attribute: y_offset” sliders to change the inputs and watch the result update live.
- Use the “Instantiate Object” button to trigger actions or reset the demo.
- Experiment freely — there's nothing to break, and every change is reversible.
What you'll explore
- Classes and Objects
- Instance Attributes and State
- Methods and Encapsulation
- Special Methods (Dunder Methods)
- Object Composition
Frequently asked questions
What does the OOP: Class vs Instance Visualizer demo do?
Instantiate Object Instance State (σ) Attribute: color_hue Attribute: y_offset Unique to this specific object. class Entity: size = 40 # No instances yet. OOP: Class vs Instance Visualizer lets you explore this hands-on instead of only reading about it.
What Intro to Python Fundamentals concept does OOP: Class vs Instance Visualizer teach?
Introduces the OOP paradigm to model real-world entities using classes and objects. It focuses on Classes and Objects, Instance Attributes and State, Methods and Encapsulation, Special Methods (Dunder Methods), Object Composition from the “Unit 6: Object-Oriented Programming (OOP)” section.
What can I control in OOP: Class vs Instance Visualizer?
The “Class Attribute: base_size”, “Attribute: color_hue”, “Attribute: y_offset” sliders change the key inputs; the “Instantiate Object” button run actions or reset the demo. Every change updates the visualization in real time, so you can see exactly how each variable affects the outcome.
How does OOP: Class vs Instance Visualizer fit into the Intro to Python Fundamentals course?
The Client Challenge course is a comprehensive introduction to computer science using the Python programming language, specifically designed for beginners. The curriculum progresses through eight structured units, movin… This demo is the interactive piece for the “Unit 6: Object-Oriented Programming (OOP)” section.

What will I understand better after using OOP: Class vs Instance Visualizer?
You'll build intuition for Classes and Objects, Instance Attributes and State, Methods and Encapsulation, Special Methods (Dunder Methods), Object Composition — and, crucially, see how they behave when you change the inputs, which is hard to get from a textbook or lecture on Intro to Python Fundamentals alone.
