This file is simply our database’s content with added formatting. Its data originates from the test data initialization module we wrote in Example 1-1 because that is the module from which Example 1-2’s self-test code imports its data. In practice, Example 1-2 itself could be imported and used to store a variety of databases and files. Notice how data to be written is formatted with the as-code repr call and is re-created with the eval call, which treats strings as Python code. That allows us to store and recreate things like the None object, but it is potentially unsafe; you shouldn’t use eval if you can’t be sure that the database won’t contain malicious code.
