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

CodeInText: 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 os
response = os.popen('ping -n 1 10.0.0.1')
for line in response.readlines():
    print line,

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

s = socket.socket(socket.PF_PACKET, socket.SOCK_RAW, socket.ntohs(0x0800))
i = 1

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

python setup.py install

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: "Select System info from the Administration panel."
