Conventions used

There are a number of text conventions used throughout this book.

Code in text: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: "Mount the downloaded WebStorm-10*.dmg disk image file as another disk in your system."

A block of code is set as follows:

import requests
from requests.auth import HTTPBasicAuth
auth = HTTPBasicAuth("root", "test")

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

my_hostname = "router01" 

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

HTTP/1.1 200 OK
Content-Type: application/json; charset=utf-8
{
   "id": 25,
   "name": "my device",
   "mac": "01-23-45-67-89-AB-CD-EF"
}

Bold: Indicates a new term, an important word, or words that you see onscreen. For example, words in menus or dialog boxes appear in the text like this. Here is an example: "On the security credentials page, navigate down to the Access Keys section and click on Create New Access Key to generate a new key pair."
