使用Python的嵌套JSON到CSV设计,python,Python,我是Python新手，正在尝试找出一个需要将嵌套的JSON解析为CSV的需求请注意，“顶部”路径在某些情况下还选择了多个对象。因此，对于每个由“paths”构造函数选项匹配的顶级对象，我们得到“m*n”行，其中“m”是“batters.batter”子路径的匹配数，“n”是“topping”子路径的匹配数 JSON: 代码：获取意外输出： "item_item_batters_batter_0_id","item_item_batters_batter_0_type","item_item_

我是Python新手，正在尝试找出一个需要将嵌套的JSON解析为CSV的需求

请注意，“顶部”路径在某些情况下还选择了多个对象。因此，对于每个由“paths”构造函数选项匹配的顶级对象，我们得到“m*n”行，其中“m”是“batters.batter”子路径的匹配数，“n”是“topping”子路径的匹配数

JSON:

代码：

获取意外输出：
