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: “The numpy library is a Python library containing numerous functions that can help us in the management of multidimensional matrices.”

A block of code is set as follows:

np.random.seed(4)
n = 1000
sqn = 1/np.math.sqrt(n)
z_values = np.random.randn(n)

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

AmznData = pd.read_csv('AMZN.csv',header=0, 
           usecols = ['Date',Close'],parse_dates=True,
           index_col='Date')

Bold: Indicates a new term, an important word, or words that you see onscreen. For instance, words in menus or dialog boxes appear in bold. Here is an example: “Select System info from the Administration panel.”
