Conventions

In this book, you will find a number of styles of text that distinguish between different kinds of information. Here are some examples of these styles, and an explanation of their meaning.

Code words in text are shown as follows: "This script waits until it receives the launch message."

A block of code is set as follows:

def count(maximum):
     value = 0
     while value < maximum:
         value = value + 1
         print "value =", value

New terms and important words are shown in bold. Words that you see on the screen, in menus or dialog boxes for example, appear in the text like this: "Select Raspbian and click on Install".
