json的编码（json.dumps()）与解码(json.loads())

从json到Python的类型转化

 

 

示例

JSON语法与语法规则
json.dumps:python对象编码成json
json.json:json串解码成python对象

#coding=utf-8
import json
data=[{"a":"A","b":(2,4),"c":3.0}]
res=repr(data)
print("data:",res)
data_json=json.dumps(data)
print(data_json)

执行结果：
>>> import json
>>> data=[{"a":"A","b":(2,4),"c":3.0}]
>>> res=repr(data)
>>> print("data:",res)
data: [{'a': 'A', 'b': (2, 4), 'c': 3.0}]
>>> data_json=json.dumps(data)
>>> print(data_json)
[{"a": "A", "b": [2, 4], "c": 3.0}]
>>>
