Interactive Demo
Conditionals and Branching Visualizer
Conditionals and Branching Visualizer is a free, interactive learning demo from the Computing course on Lykke. It helps you build intuition for Boolean expressions, Comparison operators, if-elif-else structures. Play with it directly in your browser — it features 3 sliders and 1 button. This demo lives in the “Conditionals and Branching” section of the course.

How to use this demo
- Drag the “Security Token”, “Amount: 250”, “Balance: 500” sliders to change the inputs and watch the result update live.
- Use the “Valid Token” button to trigger actions or reset the demo.
- Experiment freely — there's nothing to break, and every change is reversible.
What you'll explore
- Boolean expressions
- Comparison operators
- if-elif-else structures
Frequently asked questions
What does the Conditionals and Branching Visualizer demo do?
Conditionals and Branching Visualizer Security Token Valid Token Amount: 500 Adjust inputs to see how the logic branches in real-time. Conditionals and Branching Visualizer lets you explore this hands-on instead of only reading about it.
What Computing concept does Conditionals and Branching Visualizer teach?
Enabling programs to make decisions based on specific conditions using if-statements. It focuses on Boolean expressions, Comparison operators, if-elif-else structures from the “Conditionals and Branching” section.
What can I control in Conditionals and Branching Visualizer?
The “Security Token”, “Amount: 250”, “Balance: 500” sliders change the key inputs; the “Valid Token” 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 Conditionals and Branching Visualizer fit into the Computing course?
The Client Challenge course is a comprehensive introduction to computer science and programming using the Python language, specifically designed for beginners. It guides students through the fundamentals of computationa… This demo is the interactive piece for the “Conditionals and Branching” section.

What will I understand better after using Conditionals and Branching Visualizer?
You'll build intuition for Boolean expressions, Comparison operators, if-elif-else structures — and, crucially, see how they behave when you change the inputs, which is hard to get from a textbook or lecture on Computing alone.
