Json的编写

Json

格式:

  1. 对象以{开始 }结束

  2. 每个对象包含 名称:值

  3. 多个值用[     ]包含

  4. 值的形式为字符串,数字和布尔值

  

View Code
{
     "firstName": "John",
     "lastName": "Smith",
     "male": true,
     "age": 25,
     "address": 
     {
         "streetAddress": "21 2nd Street",
         "city": "New York",
         "state": "NY",
         "postalCode": "10021"
     },
     "phoneNumber": 
     [
         {
           "type": "home",
           "number": "212 555-1234"
         },
         {
           "type": "fax",
           "number": "646 555-4567"
         }
     ]
 }

用Python编写:

  1. 用列表和字典形式

  2. 写:

    json.dumps(data1【值】,indent=4【表示缩进4个空格】,sort_keys=True【key排序】)

  3. 读:

    dd1=json.loads(content)

  4: 代码

practice json
import json
data1 = [{'b':789,'c':\
          {"lat":"39.990","lng":"116.397"},'a':123}]
d1=json.dumps(data1,indent=4,sort_keys=True) 
f=open('/home/syu/Downloads/Vieri.json')
content=f.read()
dd1=json.loads(content)
print d1
for item in dd1:
    for file in item:
        print file,":",item[file]
