利用Python互转Json数据格式
一、将Python对象转换成json对象
|
1 2 3 4 5 6 7 8 9 10 11 |
import json def python_to_json(): """ 将python对象转换成json """ d = { 'name': 'python书籍', 'price': 62.3, 'is_valid': True } rest = json.dumps(d, indent=4) //设置首行缩进 print(rest) |
二、将json转换成python
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 |
def json_to_python(): """ 将json转换成python """ 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 } ''' rest = json.loads(data) print(rest) print(rest['name']) |
三、从文件读取内容，并转换成python对象
|
1 2 3 4 5 6 7 8 9 |
def json_to_python_from_file(): """ 从文件读取内容，并转换成python对象 """ f = open('./static/book.json', 'r', encoding='utf-8') 以只读的格式，utf-8 的编码读取 s = f.read() print(s) rest = json.loads(s) print(rest['name']) f.close() //打开文件后一定要关闭 |
