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

CodeInText: 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: "Save that file as message_vendor.py, in a folder called python."

A block of code is set as follows:

def hello_handler(event, context):
    if not event:
        return {
            "body": "Hello, world!"
        }

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

docker pull amazonlinux
docker run -it -v ~/Desktop/lolcode-lambda:/root amazonlinux /bin/bash

Bold: Indicates a new term, an important word, or words that you see on screen. For example, words in menus or dialog boxes appear in the text like this. Here is an example: "Let's click on Integration Request and see what's available."
