Binary Search Algorithm for GCSE and A Level Computer Science

Binary search is an algorithm which is fundamental to both GCSE and A Level Computer Science for all boards. It is a very clever algorithm which reduces the time needed to search for items in large datasets dramatically. It is important to note that in order to use binary search, your data must be sorted. […]

Node Class for a Linked List with Object Oriented Python

When you come to study Data Structures such as Stacks, Queues, Linked Lists and Binary Trees for A Level Computer Science, you will often make use of Object Oriented Programming. That is a bit of a double whammy if you are not yet very confident with OOP, and it can seem a bit overwhelming. I’ve […]

SQLite with Python for GCSE and A Level Computer Science

In this article we will learn how to use the SQLite database management system with Python for GCSE and A Level Computer Science. You will need to know about how SQL works for GCSE Computer Science with OCR and it will certainly help with Computer Science GCSE with Edexcel and Cambridge, although in those syllabuses […]

Graphs in Python for A Level Computer Science

Part 1 – Networkx Basics networkx is a powerful python package that allows you to easily work with graphs in Python. Combining it with the matplotlib.pyplot package even makes it simple to draw graphs. This is very useful when learning or teaching about graphs for A Level Computer Science. # Auto formatting – completely optional, […]

Counting Letters Using a Python Dictionary

Some Python developers would say that there are two fundamental constructs which form the basis of the language: lists and dictionaries. Whether or not that is true, they are both certainly very important. All the GCSE Computer Science specifications mention arrays, and although there are technical distinctions, for many purposes the notion that lists are […]

Tron Classic Arcade Game in Python

In this article we will have more fun and games with the Python Turtle Graphics Module. There are so many things you can do with this module from very basic programs to quite sophisticated applications, making it an ideal learning tool for GCSE Computer Science. One resource based on Python Turtle Graphics that is not […]

Circle Sector Challenge for GCSE Computer Science

Maths GCSE and Computer Science GCSE are often taught very separately, and yet they make excellent companions. Writing a program to explore a topic from Maths can really help to understand the topic deeply as well as providing a great opportunity to practice your coding skills. Here’s a fun challenge to keep your programming skills […]
