Python-迭代列表和字典
嗨，我在转载这个问题，但提供更多关于我试图实现的信息。在过去的几天里，它让我发疯，而我似乎无法取得进展。基本上，我有这样的数据结构：Python-迭代列表和字典,python,list,Python,List,嗨，我在转载这个问题，但提供更多关于我试图实现的信息。在过去的几天里，它让我发疯，而我似乎无法取得进展。基本上，我有这样的数据结构： data_in =\ {'map': {'command_line': u'command goes here', 'scaninfo': {u'tcp': {'method': u'syn', 'services': u'80,443'}}, 'stats': {'downhosts': u'0',

这里的任何帮助都将不胜感激 这并不难；您只需仔细查看导致所需内容的数据结构—由于格式不当，这变得更加困难，因此我重新缩进了您的输入并标记了键（
很明显，你在上一个问题中接受的答案并没有那么有帮助。那么，你为什么不回去看看其他答案，这些答案更侧重于导航你的实际结构（而不是在任何地方随机查找键）试着自己想点什么？我认为你的数据输出格式不好。你用逗号代替冒号。应该是：data_out=[{'address'：u'2a00:2384:0:208f:：13'，'hostname'：u'static.bt.com'，'ports'：[{80:{'state'：u'open'，reason'：u'syn-ack'}，{443:{'ssl_cert'：u'placeholder'，'state'：u'open'，'reason'：u'syn-ack'}]}]
是的-很抱歉修复了它。谢谢！非常感谢-我花了这么长时间盯着它看，看不到树，撞到了一堵墙。正如你所说的，由于格式不好而变得更加困难。我将详细研究你的示例。再次感谢。
