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've built an ArgumentParser method using all of the default parameters."

A block of code is set as follows:

def prod(sequence):
    p= 1
    for item in sequence:
        p *= item
    return p

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

def prod(sequence):
    p= 1
    for item in sequence:
        p *= item
    return

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

MacBookPro-SLott:Code slott$ python3 -m test_all

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: "Clicking on Continue will step through the Read Me, License, Destination Select, and Installation Type windows."

Note
