Conventions used

There are a number of text conventions used throughout this book.

Code in text: Indicates code words in the text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: "This means we can create a testing_workflow_validation.py file with the test_description function inside it."

A block of code is set as follows:

from os import listdir

import os

import xml.etree.ElementTree as ET

ayx_file = ('.yxmd', '.yxmc', '.yxwz')

files = [f for f in listdir(os.getcwd()) if f.endswith(ayx_file)]

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

ALTER TABLE "Users" ADD PRIMARY KEY ("UserId");

Bold: Indicates a new term, an important word, or words that you see on screen. For instance, words in menus or dialog boxes appear in bold. Here is an example: "In the final workflow, we can use the Output tool's Update: Insert if New option, which will keep all our records updated."
