Conventions

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

Code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "We are using again our KV file with a simple button and empty label with ID button1 and label1 respectively"

A block of code is set as follows:

<MyW>:
    Button:
        id: button1
        text: 'Hello'
        on_press: root.animate(button1)

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

 canvas.after:
 PopMatrix

Any command-line input or output is written as follows:

$ Kivy pyinstaller.py --windowed --name e1 /Users/Me/Documents/e1app/e1.py

New terms and important words are shown in bold. Words that you see on the screen, for example, in menus or dialog boxes, appear in the text like this: "We are going to use one simple Python files that will just show our Hello World text"
