python判断字典是嵌套和嵌套字典列表

#coding: utf-8
import types

#获取字典中的objkey对应的值，适用于字典嵌套
#dict:字典
#objkey:目标key
#default:找不到时返回的默认值
def dict_get(dict, objkey, default):
    tmp = dict
    for k,v in tmp.items():
        if k == objkey:
            return v
        else:
            if type(v) is types.DictType:
                ret = dict_get(v, objkey, default)
                if ret is not default:
                    return ret
    return default

#如
dicttest={"result":{"code":"110002","msg":"设备设备序列号或验证码错误"}}
ret=dict_get(dicttest, 'msg', None)
print(ret)
