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: “Using putty to connect to a Linux instance, install mysql client pkg and connect to the RDS endpoint.”

A block of code is set as follows:

Create database school;
Create table school.students (
    StudentID int primary key,
    LastName varchar(100),
    FirstName varchar(100),
    City varchar(100)  );

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

Create database school;
Create table school.students (
    StudentID int primary key,
    LastName varchar(100),
    FirstName varchar(100),
    City varchar(100)  );

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

gcloud functions deploy image_checking  --trigger-resource  z04092023-upload --trigger-event google.storage.object.finalize --runtime python37

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: “Click Explore table items.”
