Play with binary numbers, encrypt text, stylise images and make music using Python. 

Ever wondered how a computer can store all you pictures, music and even this text just using ones and zeroes? 

We'll modify Python programs and define our own functions to learn how data is represented on a computer. You'll discover how to encode text and decode text into binary, stylise and manipulate the pixels and colours that make up images, use notes and pitches to create music and learn how to customise emoji!
