Python 使用if语句循环嵌套字典
我有很多内部字典，我的逻辑有点不正确，因为我的输出接近我想要完成的，但还没有达到。我想连接来自内部字典的两个变量的值 虽然在循环中，我的变量打印正确，但当我使用另一个变量连接这两个变量时，我只收到几个值。此数据来自JSON结构 代码： BulkyItemInfo的输出：Python 使用if语句循环嵌套字典,python,dictionary,Python,Dictionary,我有很多内部字典，我的逻辑有点不正确，因为我的输出接近我想要完成的，但还没有达到。我想连接来自内部字典的两个变量的值 虽然在循环中，我的变量打印正确，但当我使用另一个变量连接这两个变量时，我只收到几个值。此数据来自JSON结构 代码： BulkyItemInfo的输出： 1, Carpet 1, Carpet 1, Chair 1, Carpet 1, Chair 1, Desk 1, Carpet 1, Chair 1, Desk 1, Wood Bundles 1, Car

请注意，我选择在打印之前将所有内容存储在字符串中。这不是必须的，但它是获得所需输出的一种简单方法。为什么不使用标准库的模块？我认为您完全误解了这一点。原因可能是您没有明确说明您想要实现什么或您的问题是什么。那么，请告诉我，问题中显示了所需的输出，从上面的JSON中，我想循环并获得一个格式化的字符串。我能够迭代json，但我的逻辑在循环中不正确。我从一个web服务中使用这个json，并且已经在使用json模块了，所以这些信息是非常无用的。你的问题仍然不清楚你想要实现什么。只要记住你深陷其中，我们不是。请提供一份报告。
