如何从json字符串中获取值？

标签： python json

我正在为xboxapi.com使用api，其大部分信息都是用json格式化的。

以下json代码包含有关Xbox当前“Games with Gold”优惠的信息。我想将每个游戏名称设置为自己的变量，例如：

Game1 = Sleeping Dogs: Definitive Edition
Game2 = Outlast

等等。我试图提取的关键是“TitleName”，我多次看到它：

#This Variable holds the data 
GWG = api.get_xboxone_gold()
json_str = json.dumps(GWG) 
resp = json.loads(json_str)
print (resp) 
print(resp["TitleName"])

1 个答案:

答案 0 :(得分：1)

看起来你已经解析了你收到的任何JSON，所以下一步是解析字典。

  

print(resp["TitleName"])

     

无论我尝试的方法，我都找不到“TitleName”

将您的JSON放在这里。 （不是python数据，实际的JSON）https://jsonformatter.curiousconcept.com

你会清楚地注意到TitleName不是顶级元素。你必须循环黄金交易元素。

例如，列表理解

names = [x['TitleName'] for x in data['DealsWithGold']]

或者，您可以扩展以获取更多数据而不仅仅是标题

的更详细的版本 
names = [] 
games = data['DealsWithGold']
for game in games:
    names.append(game['TitleName'])
