将python对象转换成json

import json

def dict_to_json():

"""字典转化为json"""

d = {

'name': '斗破苍穹',

'price': 99.8

}

res = json.dumps(d)

print(res)

if __name__ == '__main__':

res = dict_to_json()

结果 : {"name": "\u6597\u7834\u82cd\u7a79", "price": 99.8}

将json转换成python

import json

def json_to_dict():

data = '''

{

"name": "Python书籍",

"origin_price": 66,

"pub_date": "2018-4-14 17:00:00",

"store": ["京东", "淘宝"],

"author": ["张三", "李四", "Jhone"],

"is_valid": true,

"is_sale": false,

"meta": {

"isbn": "abc-123",

"pages": 300

},

"desc": null

}

'''

res = json.loads(data)

print(res)

return res

if __name__ == '__main__':

res1 = json_to_dict()

print(type(res1))

结果 : {'name': 'Python书籍', 'origin_price': 66, 'pub_date': '2018-4-14 17:00:00', 'store': ['京东', '淘宝'], 'author': ['张三', '李四', 'Jhone'], 'is_valid': True, 'is_sale': False, 'meta': {'isbn': 'abc-123', 'pages': 300}, 'desc': None}

从文件读取内容，并转换成python对象

import json

import os

def json_to_py_from_file():

""" 从文件读取内容，并转换成python对象 """

dir1 = os.getcwd()

print(dir1)

# 以只读方式打开文件。文件的指针将会放在文件的开头。这是默认模式。

f = open('./static/book.json', 'r', encoding='utf-8')

s = f.read()

print(s)

rest = json.loads(s)

print(rest['name'])

f.close()

book.json文件内容

{

"name": "Python书籍",

"origin_price": 66,

"pub_date": "2018-4-14 17:00:00",

"store": ["京东", "淘宝"],

"author": ["张三", "李四", "Jhone"],

"is_valid": true,

"is_sale": false,

"meta": {

"isbn": "abc-123",

"pages": 300

},

"desc": null

}
