"JSON is similar to Python code, except for the `null` value and the prohibition of commas at the end of lists. The basic types are objects (dicts), arrays (lists), strings, numbers, Boolean values and `null`. All keys of an object must be strings. There are several Python libraries for reading and writing JSON data. I will use [json](https://docs.python.org/3/library/json.html) from the Python standard library here. To convert a JSON string into Python form, I use `json.loads`:"
