#1.字典类型数据转json
import json
user={"username":"zhangsan","age":18} #字典类型
print(user,type(user))
data=json.dumps(user) #转json长得像字典的字符串
print(data,type(data))
#2.json字符串转字典
json_str='{"user":"hehe","money":10000}'
print(json_str,type(json_str))
data1 = json.loads(json_str) #转为字典类型
print(data1,type(data1))
print(data1['user'],data1['money'])
