Vectorization vs. Iteration Demo
Vectorization vs. Iteration Demo is a free, interactive learning demo from the pandas documentation course on Lykke. It helps you build intuition for Vectorization, Split-Apply-Combine, Groupby, Summary Statistics. Play with it directly in your browser — it features 1 slider and 2 buttons. This demo lives in the “Data Manipulation and Summary Statistics” section of the course.
How to use this demo
- Drag the “ARRAY SIZE: 100” slider to change the inputs and watch the result update live.
- Use the “RUN COMPARISON”, “RESET” buttons to trigger actions or reset the demo.
- Experiment freely — there's nothing to break, and every change is reversible.
What you'll explore
- Vectorization
- Split-Apply-Combine
- Groupby
