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: "From the installation directory, we just need to invoke python.exe, which will invoke the Python interpreter."

A block of code is set as follows:

#PowerShell sample code
$myvalue=$args[0]
write-host ("Argument passed to Powershell is "+$myvalue)

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

python checkargs.py 5 6

New terms and important words are shown in bold.
