[英]How to generate a json file in python from nested array/dictionary/object
[英]How can someone create a python key:value dictionary from a nested array in a JSON file with multiple lines in python?
我有一个JSON文件,其值在[]括号中,如图所示。 我正在尝试创建一个显示[id_value:text_value。]的[key:value]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。
到目前为止,这是我编码的内容,但无法很好地得到这些值。
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
