Dumping and loading with JSON

What is JSON? A section from the www.json.org web page states that:

JSON (JavaScript Object Notation) is a lightweight data-interchange format. It is easy for humans to read and write. It is easy for machines to parse and generate. It is based on a subset of the JavaScript Programming Language, Standard ECMA-262 3rd Edition - December 1999. JSON is a text format that is completely language independent but uses conventions that are familiar to programmers of the C-family of languages, including C, C++, C#, Java, JavaScript, Perl, Python, and many others. These properties make JSON an ideal data-interchange language.

This format is used by a broad spectrum of languages and frameworks. Databases such as CouchDB represent their data as JSON objects, simplifying the transmission of data between applications. JSON documents have the advantage of looking vague like Python list and dict literal values. They're easy to read and easy to edit manually.
