Python 使用json数据解析错误：字符串索引必须是整数

我正在尝试解析Json。我已经放置了json结构的图像。请看一看

我收到的错误是：

print("title: "+json_data["title"])
TypeError: string indices must be integers

我的JSON结构如下：

问题是因为最后的

命令

：

{
    "hasmore": 1,
    "numhits": 1000
}

您的内部循环希望处理包含dict的列表，因此当它点击该dict时，它会尝试在“hasmore”键上执行

json_data[“title”]

这是一个修复过的版本

您没有使用

json.loads

将字符串解析到字典中。使用了json.loadWhat@JimFasarakisHilliard所说的，或者

数据

没有您认为的结构。在内部for循环之前添加

print（json\u inner\u array）

，查看第二个循环实际迭代的内容。“used the json.load”编辑您的问题并向我们展示您是如何使用它的。此时，您提供的代码片段没有显示

json

库的任何用法。有一点是肯定的：如果您收到此消息，那么此时

json\u数据

是一个字符串。FWIW

json

拒绝解析您发布的json片段。请贴一张合适的MCVE@AbhishekKaushik您是否有可能更改返回的JSON（或请求更改）？如果数组中的每个值都具有相同的类型，那么JSON的解析就会更加清晰。@AbhishekKaushik我同意chepner的观点，如果你能改变JSON结构，你应该这样做！依我看，外层应该是一个目录，而不是一个列表。该dict可以包含一个用于额外信息的dict和一个主要数据dict的列表，没有必要将每个dict包装在自己的1项列表中。@chepner谢谢，但我无法更改结构，因为我是从其他人那里获得的，用于执行一些实验。。我在这个Json中发现了困难。结构不是很清楚。谢谢大家的帮助和支持。
