我正在處理2個混合json文件和收集的音頻（大約400個json文件）的文件夾，如下所示：{ "id":"c79c32e7-6665-4c5e-9458-d15930488263", "age":"34", "gender":"m", "healthStatus":"healthy", "audioFiles":[ "1585940317337_sentence_healthy_m_34_c79c32e7-6665-4c5e-9458d15930488263.wav", "1585940317337_cough_healthy_m_34_c79c32e7-6665-4c5e-9458-d15930488263.wav", "1585940317337_breath_healthy_m_34_c79c32e7-6665-4c5e-9458d15930488263.wav" ]}我想檢索 ，并將它們合并到一個JSON文件中，以便在python中進行分析。agegenderhealthStatus為此，我寫道：from pathlib import Pathimport jsondata_folder = Path("/Users/jiani/Desktop/Voicemed/#ml/cough_classification-original_experiment/new_data/meta1")read_files = glob.glob("data_folder/.json")output_list = []for f in read_files: with open(f, "rb") as infile: output_list.append(json.load(infile))with open("merged_file.json", "w") as outfile: json.dump(output_list, outfile)然后我打印了，但我得到了一個空的。我已經閱讀了一些相關的解決方案，但我仍然無法得到答案。有人可以幫助我嗎？output_list

試試這個：
from os import listdir
from os.path import isfile, join
import json
data_folder = "full/path/to/jsons"
files = [join(data_folder,f) for f in listdir(data_folder) if isfile(join(data_folder, f)) and f.endswith(".json")]
output_list = []
for file in files:
with open(file, "r") as f:
output_list.append({k:v for k,v in json.load(f).items() if k in ["age","gender","healthStatus"]})
with open("merged_file.json", "w") as outfile:
json.dump(output_list, outfile)
