Now available with text that lights up as you read along and playful images and sounds.

Avoiding computer jargon, this book guides children through creating computer programs starting with the very basics. Computer Coding for Kids is the only programming book that teaches both Scratch and Python programming languages, with illustrated, simple, step-by-step explanations that make the complex art of computer programming clear for the complete beginner. Starting with simple explanations of programming basics, it progresses to more advanced projects where children can build their own games.

See how it works by creating this simple program that writes a message on the screen. Working in IDLE Different windows Python uses two different windows – the “shell” window and the “code” window (see pages 106–107). We’ve given them different colours to tell them

SEE ALSO  92–93 Introducing IDLE There are two different windows to choose from in IDLE. The code window can be used to write and save programs, while the shell window runs Python instructions straight away.  96–97 Ghost game The code window ▽ Running programs So far in this book, the code window has been used to write programs. You enter the program, save it, run it, and the output appears in the shell window. This process is used for running Python programs. Programs always have to

through every item in a list. This program says “Hello” to a series of names, one after the other. ◁ Adding lists Two lists can be added together. The new list will contain the items from both of the old lists. ▽ Lists in lists The items in a list can be lists themselves.

As the list is inside square brackets, it becomes an individual item within the
