In the real world, many of the problems that we are trying to solve arise and exist within the physical realm. Using computer science and code to solve some of these problems requires the programmer to capture what is happening in the physical world with data that the computer can understand, process and manipulate. As the final course in the Basics sequence, Jr Python 4 serves as a primer on data types and structures to Code Campers before they move on to Principles 3. In this course, kids will familiarise themselves with the different data types, both simple and complex. Through the manipulation of such data using code, they will learn to appreciate how each of the different data types are used by programmers to model different features of real-world problems. This will require them to synthesise and rely on all the coding tools, decomposition and abstraction skills in the preceding courses in order to model the real-world. After this course, they will have a stronger foundation upon which to layer on further concepts relating to complex data structures at a faster pace in the Principles sequence.
