python中json对象的内部字典解析

我有一个列表，叫做filelist=[] 我在其中附加了一些键值对的字典

filelist.append({"url": url, "exename": ename, "filename": fname}] as I loop through a set of files.
Later, loads() the below json object to a "json" key: 

for file in filelist: file["json"] = json.loads(json)

我可以毫不费力地提取字典值的第一层，即

for files in filelist:
    print files["json"]["response_code"]

>>> 1

然而，我在获取我假设的内部字典时遇到了问题 文件[“json”][“扫描”] 例如：

for files in filelist:
    for avvendors in files["json"]["scans"]

我对提取“检测到的”键非常感兴趣，但python似乎没有将“扫描”键作为字典加载，而是将其存储为字符串。我正在考虑对内部字典进行第二次加载（），看看会发生什么

for stuff in avvendors:
    if stuf["detected"]:
        #do something

我真的不确定这里发生了什么。我知道我可能会找到答案，但了解一下python在内部如何处理json会很好。而且，我要到星期一或星期二，甚至星期三才有机会做这件事，悬念要把我累死了

以下是完整的可读性块：

对于文件列表中的文件： 对于文件[“json”][“扫描]”中的AVF供应商： 如果供应商[“检测到”]： #做些有用的事

迭代dict时要小心。它只返回键。如果需要键和值，请使用

.iteritems（）

方法（或在Python3中，

.items（）

）：

---

在您的例子中，

scans

键的值是一个dict:

“scans”：{“nProtect”：…}

记住，在Python3.x中，这只是

dict.items（）

。因此python可能将内部字典作为字典加载，我错误地认为它只是作为字符串加载？

json.loads（）

返回Python对象，例如dict的列表。因此，是的，内部字典是一个dict，而不是一个字符串。不过，现在我想起来了，“true”变为true，“antivi”变为u'antivi'等。当在提供的整个混乱中使用print时，谢谢！

for files in filelist:
   for avvendor, stuf in files["json"]["scans"].iteritems():
       if stuf["detected"]:
          #do something
