Question statement

The preamble of this question calls https://fakerapi.it/api/v1/books?_quantity=1 to get information about a randomly generated fake book. This particular task could be done entirely in Numbas, but it demonstrates the principle of requesting data from an external source.

If the request succeeds, then the variable book is set with the returned data. The variables title and author are both defined to extract information from book.

Give any introductory information the student needs.

			Name	Type	Generated Value

book	dict	Dictionary with 9 entries
author	string	Rosalyn Kub
title	string	Dormouse, not.

Automatically regenerate variables?

Description

The data about the book is stored in this variable once it's received from the external API. A default value is given so that the editor doesn't complain about an undefined variable, and to document the variable's structure.

Describe what this variable represents, and list any assumptions made about its value.

Can an exam override the value of this variable?

Generated value: `dict`

[ "id": 1, "title": safe("Dormouse, not."), "author": safe("Rosalyn Kub"), "genre": safe("Et"), "description": safe("Mock Turtle, and said to the croquet-ground.
