Python objects and JSON convert to each other __JS

One, Python support for JSON

Starting with python2.6, the Python standard library has added support for JSON, which requires only import JSON when manipulating JSON. two, Python objects converted to JSON strings

When converting a Python object to a JSON string, you only need the following knowledge:

Conversion rules for 1.python objects to JSON strings:

Python	JSON
Dict	Object
List, tuple	Array
STR, Unicode	String
int, long, float	Number
True	True
False	False
None	Null

2. The main use of the following functions:

Json.dumps ()

The specific parameters of the function (see the link in the appendix):
Json.dumps (obj, Skipkeys=false, Ensure_ascii=true, Check_circular=true, Allow_nan=true, Cls=none, Indent=None, Separators=none, encoding= "Utf-8", Default=none, Sort_keys=false, **kw) example

Test code:

#构造字典
Python2json = {}
#构造list
listdata = [1,2,3]
python2json["listdata"] = Listdata
Python2json ["strdata"] = "Test python obj 2 json"

#转换成json字符串
json_str = Json.dumps (Python2json)
print Json_str

Conversion results:

{
    "listdata": [
        1,
        2,
        3
    ],
    "strdata": "Test Python obj 2 json"
}

Third, JSON string converted to Python object

In the same vein, converting a JSON string into a Python object requires only the following knowledge:

Conversion rules for 1.json strings to Python objects:

JSON	Python
Object	Dict
Array	List
String	Unicode
Number (int)	int, long
Number (real)	Float
True True
False	False
Null	None

2. The main use of the following functions:

Json.loads ()

The specific parameters of the function (see the link in the appendix):
Json.loads (s[, encoding[, cls[, object_hook[, parse_float[, parse_int[, parse_constant[, object_pairs_hook[, **kw]]]] ]]) example

Test code:

str = ' {listdata ': [1, 2, 3], "strdata": "Test Python obj 2 json"} '
Json2python = json.loads (str)
print type (JSON 2python)

Conversion results:

<type ' Dict ' >
