我如何将其解析为以下列表：

objectLst = ['Floor-...', 'Room-...', 'Wall-...'] etc
keys = [['floor_type', 'level_name', 'revit_id', 'thickness', 'material' etc],['number', 'occupancy', 'floor_finish', 'wall_finish','name', 'occupancy' etc],['wall_type','level_name' etc]]
values = [all values from key/value relationship in json file like above keys]

值/键的数量因每个对象而异，所以我有点好奇如何将它正确地解析为python中的列表。所有帮助表示赞赏。

Answer 1

使用list comprehensions：

data = json.load(data_file)

objects = data.keys()
keys = [d.keys() for sub_dict in data.values()]
values = [d.values() for sub_dict in data.values()]

对于objects，您只需要顶级词典中的键，因此非常简单。对于包含键列表或每个子词典中的值的列表，您需要迭代这些子词典（我称之为sub_dict）。每个子字典都是顶级字典的值，因此要迭代它们只需调用data.values()。
