Python JSON TypeError : list indices must be integers or slices, not str

by Code Error
Posted By: Anonymous

I am trying to loop through a dataframe but I am getting a for row in i["Attachments"]: TypeError: list indices must be integers or slices, not str
My JSON file has Attachments yet it is giving me errors. I have possibly tried all ways from Stackoverflow to get this issue solved, but to my dismay none of them really worked.
this is my Json file

idx.json

And this is my code:

json_data = pd.read_json("idx.json", lines=True)
        for i in json_data["Results"]:
            for row in i["Attachments"]:
                try:
                   # rest of code

I am able to get the values for Results column but getting issues for Attachments. Please help me out!

Solution

I’ve modified the code a little and have used dictionary for easier access and it is working great.

import json

# Opening JSON file
f = open('data.json',)

# returns JSON object as
# a dictionary
data = json.load(f)

# Iterating through the json
# list
for i in data['Results']:
    for row in i["Attachments"]:
        print("Emiten_Code is ", row["Emiten_Code"], ", File_ID is ",row["File_ID"])

# Closing file
f.close()

"""
