I have a following folder structure:

Directory

- Subdirectory 1:

file.json

- Subdirectory 2:

file.json

- Subdirectory 3:

file.json

- Subdirectory 4:

file.json

How do I read these JSON files using Pandas?

解決方案

You could do the following:

import glob, os

working_directory = os.getcwd()

sub_directories = [active_directory + "/" + x for x in os.listdir(working_directory) if os.path.isdir(active_directory + "/"+x)]

all_json_files = []

for sub_dir in sub_directories:

os.chdir(sub_dir)

for file in glob.glob("*.json"):

all_json_files.append(sub_dir + "/" + file)

#Get back to original working directory

os.chdir(working_directory)

list_of_dfs = [pd.read_json(x) for x in all_json_files]

From there, if all json files have the same structure, you could concatenate them to get one single dataframe:

final_df = pd.concat(list_of_dfs)

總結

以上是生活随笔為你收集整理的python读取json文件转化为list_Python从所有子目录读取JSON文件的全部內容，希望文章能夠幫你解決所遇到的問題。
