## Main Development
1. Pupils should be asked what kind of information they have been using in the previous lessons; in other words, the things they’ve been able to change. They have been able to change the time to sleep and the note to play. Ask them what kind of information this is; they’re all numbers. Explain that a number is a kind of data, and there are many others that computers may understand.

This list of numbers has special syntax to tell the computer that it’s a list. Firstly, it has to start with a [ and end with a ]. Secondly, each number in the list has to be separated from the other numbers with a comma.
