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 h2o.explain and h2o.explain_row methods bundle a set of explainability functions and visualizations for global and local explanations, respectively."

A block of code is set as follows:

from pysparkling import *

import h2o

hc = H2Ocontext.getOrCreate()

hc

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

PYSPARK_DRIVER_PYTHON="ipython" \
PYSPARK_DRIVER_PYTHON_OPTS="notebook" \
bin/pysparkling

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: "Under the Admin menu in Flow, the top three options are Jobs, Cluster Status, and Water Meter."
