[Tutor] python: extracting nested json object from multiple files, write to separate text files

[Gary LaRose]

Thank you for you guidance.
I am attempting to extract nested json object in multiple json files and write to individual text files.
I have been able to get a non-nested element ['text'] from the json files and write to text files using:

import os, json
import glob

filelist = glob.glob('./*.json')

for fname in filelist:
     FI = open(fname, 'r', encoding = 'UTF-8')
     FO = open(fname.replace('json', 'txt'), 'w', encoding = 'UTF-8')
     json_object = json.load(FI)
     FO.write(json_object['text'])

FI.close()
FO.close()

I have set the working directory to the folder that contains the json files.
Below is example json file. For each file (2,900), I need to extract 'entities' and write to a separate text file:
