json的使用

json.dumps()将python数据转换为json

data = {"name":"Kidd",
        "age":17,
        "sex":""}
dumps = json.dumps(data)
print(type(dumps))

json.loads()将json数据转换为python

import json
data = {"name":"Kidd",
        "age":17,
        "sex":""}
dumps = json.dumps(data)
print(type(dumps))
loads = json.loads(dumps)
print(type(loads))

json.dump()将数据写成json文件

import json
data = {"name":"Kidd",
        "age":17,
        "sex":""}
with open('data.json',"a+") as f:
    json.dump(data,f)

json.load()读取json文件

import json
with open('data.json',"r") as f:
    data = json.load(f)
