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: “Mount the downloaded WebStorm-10*.dmg disk image file as another disk in your system.”

A block of code is set as follows:

import pandas as pd
orig_df = pd.DataFrame({
    'age': [45, 43, 54, 56, 54, 52, 41],
    'gender': ['M', 'F', 'F', 'M', 'M', 'F', 'M'],
    'group': ['H1', 'H1', 'H2', 'H3', 'H2', 'H1', 'H3'],
    'target': [0, 0, 1, 0, 1, 1, 0]})

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

in_encrypt = open("molecule_enc.bin", "rb")
nonce, tag, ciphertext = [in_encrypt.read(x) for x in (16, 16, -1) ]
in_encrypt.close()

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

python -m pytest

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: “You might be able to find other images of cracked products or you could generate new images using a process called data augmentation.”
