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 numpy as np
x = np.array([[1,2,3],[4,5,6],[1,2,5]])
y = np.linalg.inv(x)
print (y)
print (np.dot(x,y))

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

import numpy as np
x = np.array([[1,2,3],[4,5,6],[1,2,5]])
y = np.linalg.inv(x)
print (y)
print (np.dot(x,y))
