Kai had many questions when he unexpectedly found himself trapped inside a giant robot. Kai was just a young boy, but somehow he had become isolated from the outside world, and the only way to communicate with others is through the robot. Some of these questions are “what is the language of this robot (Python)?”, “how can I learn it?”, and “how can I use this language to send and receive messages to and from the outside world?” The answers to these questions and more will be found in this chapter.
