我有一个JSON文件,其值在[]括号中,如图所示。我想创造一个[关键字:值]显示[id\u值:text\u值]的字典

{"id":6127465, "users":{"name":[{"dr_info":[28,37],"text":"trees"}],"favorites":[]}}
{"id":9285628, "users":{"name":[{"dr_info":[16,24],"text":"grass"}, {"id_info":[30,34],"text":"trees"}],"favorites":[]}}
{"id":7625927, "users":{"name":[{"dr_info":[18,23],"text":"grass"}],"favorites":[], "type" : "photo"}}
{"id":8725946, "users":{"name":[{"dr_info":[23,33],"text":"grass"}, {"id_info":[37,41],"text":"trees"}],"favorites":[]}}

以上面的前两行JSON为例。字典的输出为:


[6127465:'树']

[9285628:'草','树']等等。你知道吗


这是我到目前为止编写的代码,但是我不能很好地得到值。你知道吗

dict={}
with open(fileName, 'r') as file_to_read:
    for line in file_to_read:
        data = json.loads(line)
        json_tree = objectpath.Tree(data)
        json.dumps(data, ensure_ascii=True)
        dict[json_tree.execute('$.id')] = json_tree.execute('$.users.name.text')
return dict

新建编辑。(回答)

dict={}
    with open(fileName, 'r') as file_to_read:
        for line in file_to_read:
            data = json.loads(line)
            json_tree = objectpath.Tree(data)
            json.dumps(data)
            dict[json_tree.execute('$.id')] = list(json_tree.execute('$.users.name.text'))
    return dict
