Conventions used

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: "For the handler, specify the value as lambda_function.lambda_handler."

A block of code is set as follows:

print('Loading function') def respond(err, res=None): return { 'statusCode': '400' if err else '200', 'body': err if err else res, 'headers': { 'Content-Type': 'application/json', }, } 

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

print('Loading function') 
 
def respond(err, res=None): 
    return { 
        'statusCode': '400' if err else '200', 
        'body': err if err else res, 
        'headers': { 
            'Content-Type': 'application/json', 
        }, 
    } 

Bold: Indicates a new term, an important word, or words that you see onscreen. For example, words in menus or dialog boxes appear in the text like this. Here is an example: "Click on the API's name, Serverless Weather Service, to drill down into its configuration."
