分析时出现json数据错误：字符串索引必须是整数

Question

我正在尝试解析Json。我已经把json结构的图像。请看一下。在

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：

^{pr2}$

我使用的代码是：

这是我加载json数据的代码。在

^{3}$

Answer 1

问题是因为最后的dict：

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

您的内部循环期望处理包含dict的列表，因此当它命中该dict时，它试图对“hasmore”键执行json_data["title"]。在

这是一个修复版本。在

^{pr2}$

输出

如果需要读取最后dict中的数据，只需添加一个else块。例如

for json_inner_array in data:
    if isinstance(json_inner_array, list):
        for json_data in json_inner_array:
            print("title: "+json_data["title"])
            print("snippet: ", json_data["snippet"])
            print("id: ",json_data["id"])
            print("url: ",json_data["url"])
            print("score:",json_data['score'])
    else:
        print("\nExtra info:")
        print("hasmore:", json_inner_array["hasmore"])
        print("numhits:", json_inner_array["numhits"])
