This page provides a basic overview of JSON.
**Note: any specifics (such as functions) are in terms of Python**

IMPORTANT: json package must be imported to Python script.

import json

• JavaScript Object Notation
• Syntax for storing and exchanging data.
• Web browser to server communication must be done using text.
• JSON <---> Python Dictionary (conversion between types can occur in both directions).

• JSON Objects are text enclosed in curly braces {}
• Key/Value pairs: JSON writes text in a way that formats the data into key value pairs.

• key names must be enclosed using double quotations ""
• values can be of the following types

Datatype	Example
string	"example string"
number	65.4
JSON Object	{"key" : "internal object"}
array	[{"obj1" : "exampVal1"}, {"obj2" : "exampVal2"}]
boolean	true / false
null	null

• loads(<jsonObject>)

• converts a JSON string to a Python dictionary

• dumps(<pythonObject>)

• converts a Python Object to JSON
• convertible Python Objects:

Python Object	JSON Type
dictionary	Object
list	array
tuple	array
string	string
int	Number
float	Number
True	true
False	false
None	null

• additional arguments for dumps()

• indent = #
