#把字符串转载为json：loads
json_1=json.loads(test)

#把json格式化为str：dumps
json_2=json.dumps(json_1,ensure_ascii=False,indent=4)

#json中的索引
print(json_1['data'])
print(json_2)

#json中的遍历
for itme in json_1['data']:
    print(itme)

#把json转为字典，进行遍历
ls_all=[]
for dic in json_1['data']:
    ls=[]
    for k,v in dict(dic).items():
        #这里的dic[k]和v是同一个变量

        ls.append(v)
    print()
    #把一个列表放入另一个列表
    ls_all.append(ls)
print(ls_all)
