Pizza Order System

Programming Fundamentals•2/5 marks

A pizzeria tracks orders using parallel arrays. Write a program that: • Creates two arrays: `sizes` containing ["Small", "Medium", "Large", "Small", "Medium"] and `prices` containing [8.00, 10.00, 12.00, 8.00, 10.00] • Calculates and displays the total value of all orders • Counts and displays how many Small pizzas were ordered • Finds and displays the most expensive single order Use loops to process the arrays.

# Pizza Order System sizes = ["Small", "Medium", "Large", "Small", "Medium"] prices = [8.00, 10.00, 12.00, 8.00, 10.00] # Write your code here

About This Platform

I originally built this so my students could get extra support with Python when coding at home. I've had good engagement from my students so have since expanded it to cover the whole spec and made it available for other teachers.

It's now 600+ OCR-style questions, interactive tools for flowcharts and logic gates, a Python interpreter with better error messages than IDLE, and AI marking that follows exam-style rubrics. My students get feedback straight away instead of waiting days. I spend less time marking and more time teaching.

This is still very much under development. I'm constantly fixing bugs and adding new features. If something's not working or you'd like to see something added, I'd love to hear from you.
