JSON or Python dict / list decoding problem - python

I have been using the Python script below to try and retrieve and extract some data from Flightradar24, it would appear that it extracts the data in JSON format and will print the data out ok fully using json.dumps, but when I attempt to select the data I want (the status text in this case) using get it gives the following error:
'list' object has no attribute 'get'
Is the Data in JSON or a List ? I'm totally confused now.
I'm fairly new to working with data in JSON format, any help would be appreciated!
Script:
import flightradar24
import json
flight_id = 'BA458'
fr = flightradar24.Api()
flight = fr.get_flight(flight_id)
y = flight.get("data")
print (json.dumps(flight, indent=4))
X= (flight.get('result').get('response').get('data').get('status').get('text'))
print (X)
Sample of output data:
{
"result": {
"request": {
"callback": null,
"device": null,
"fetchBy": "flight",
"filterBy": null,
"format": "json",
"limit": 25,
"page": 1,
"pk": null,
"query": "BA458",
"timestamp": null,
"token": null
},
"response": {
"item": {
"current": 16,
"total": null,
"limit": 25
},
"page": {
"current": 1,
"total": null
},
"timestamp": 1546241512,
"data": [
{
"identification": {
"id": null,
"row": 4852575431,
"number": {
"default": "BA458",
"alternative": null
},
"callsign": null,
"codeshare": null
},
"status": {
"live": false,
"text": "Scheduled",
"icon": null,
"estimated": null,
"ambiguous": false,
"generic": {
"status": {
"text": "scheduled",
"type": "departure",
"color": "gray",
"diverted": null
},

You can use print(type(variable_name)) to see what type it is. The .get(key[,default]) is not supported on lists - it is supported for dict's.
X = (flight.get('result').get('response').get('data').get('status').get('text'))
# ^^^^^^^^ does not work, data is a list of dicts
as data is a list of dicts:
"data": [ # <<<<<< this is a list
{
"identification": {
"id": null,
"row": 4852575431,
"number": {
"default": "BA458",
"alternative": null
},
"callsign": null,
"codeshare": null
},
"status": {
This should work:
X = (flight.get('result').get('response').get('data')[0].get('status').get('text')

The issue, as pointed out by #PatrickArtner, is your data is actually a list rather than a dictionary. As an aside, you may find your code more readable if you were to use a helper function to apply dict.get repeatedly on a nested dictionary:
from functools import reduce
def ng(dataDict, mapList):
"""Nested Getter: Iterate nested dictionary"""
return reduce(dict.get, mapList, dataDict)
X = ng(ng(flight, ['result', 'response', 'data'])[0], ['status'[, 'text']])

how do I access this json data in python?

hi I'm pretty new at coding and I was trying to create a program in python that reads and save in another file the data inside a json file (not everything, just what I want). I googled how to parse data but there's something I don't understand.
that's a part of the json file:
`

I can access profileChanges. I wrote this to create another json file with only the profileChanges things:
`
myjsonfile= open("file.json",'r')
jsondata=myjsonfile.read()
obj=json.loads(jsondata)
ciso=obj['profileChanges']
for i in ciso:
print(i)
with open("file2", "w") as outfile:
json.dump( ciso, outfile, indent=1)
the issue I have is that I can't access "profile" (inside profileChanges) in the same way by parsing the new file and I have no idea on how to do it
Access to JSON or dict element is realized by list indexes, please look at below example:
a = [
{
"friends": [
{
"id": 0,
"name": "Reba May"
}
],
"greeting": "Hello, Doris Gallagher! You have 2 unread messages.",
"favoriteFruit": "strawberry"
},
]
b = a['friends']['id] # b = 0
I've added a couple of closing braces to make your snippet valid json:
s = '''{

d = json.loads(s)
print(d['profileChanges'][0]['profile']['version'])
This prints refund_teddy_perks_september_2022
Explanation:
d is a dict
d['profileChanges'] is a list of dicts
d['profileChanges'][0] is the first dict in the list
d['profileChanges'][0]['profile'] is a dict
d['profileChanges'][0]['profile']['version'] is the value of version key in the profile dict in the first entry of the profileChanges list.

Getting specific lines from a print in Python with Spotipy

I am writing some code with Python and Spotipy and I'm relatively new to coding. I have some code that get all the info about a Spotify playlist and prints it out for me:
from spotipy.oauth2 import SpotifyClientCredentials
import spotipy
import json
client_credentials_manager = SpotifyClientCredentials()
sp = spotipy.Spotify(client_credentials_manager=client_credentials_manager)
playlist_id = 'spotify:playlist:76CVeJDw2b90up5PgkZXyU'
results = sp.playlist(playlist_id)
#print(json.dumps(results, indent=4))
print((json.dumps(results, indent=4)))
It works well and gives me all the info. My problem is that I only need specifics from the print:

From this long print I somehow need to extract the Artist and the song title and preferably make it into a variable. Also not sure how this would work if there are multiple songs in a playlist.
It's also a solution if I can print out only the Artist and the title of the song without printing out all the information.
Based on your posted example it appears that you have only 1 song named "Africa" by artist "TOTO". Copying the track to have two songs, I added another track with two artists for testing the arrays.
If that json is loaded into a variable named results then (as #xcmkz said) you have a python dictionary and can process accordingly.
Try working with the following to transverse through your dict appending artists and songs to lists:
song_dict = {}
for track in results['tracks']['items']:
song_name = track["track"]["name"]
a2 = []
for t1 in track['track']['artists']:
a2.append(t1['name'])
song_dict.update({song_name: a2})
print(f'Dictionary of Songs and Artists:')
for k, v in song_dict.items():
print(f'Song --> {k}, by --> {", ".join(v)}')
Results:
Dictionary of Songs and Artists:
Song --> Africa, by --> TOTO
Song --> Just Another Silly Song, by --> Artist 2, Artist 3
sp.playlist returns a dictionary, so you can simply access its values by their keys. For example:
>>> results['name']
'TEST'
JSON is a data serialization format, ie a standardized way of representing objects as pure text and parsing them back from the text. json.dumps therefore converts the dictionary object to a string of text. This is useful if you want to for example save the results to a file and load it back later. You don't need it to access contents from results.
(This is a playlist though—you will need to get information on each song/track to get its artist and name.)

Parsing list of dictionaries in a dictionary to retrieve a specific key's value from each dictionary

I got a JSON response and converted it to a python dictionary using json.loads(). So the dictionary looks like this:
{u'body': u'[{"id":"1","entity":"zone","status":"PROCESSING","url":null,"createdOn":"2019-10-11T05:49:11Z"},{"id":"2","entity":"floor","status":"FAILED","url":null,"createdOn":"2019-10-11T05:49:15Z"},{"id":"3","entityType":"apartment","status":"SUCCESS","url":null,"createdOn":"2019-10-11T05:49:18Z"}]',u'isBase64Encoded': False, u'statusCode': 200}
I named this as testStatusList. I want to retrieve the value of "status" key of every dictionary inside "body". I was able to retrieve the "body" by giving body = testStatusList['body']. Now, the dictionary looks like:
[
{
"id": "1",
"entityType": "zone",
"status": "PROCESSING",
"url": null,
"createdOn": "2019-03-07T12:47:10Z"
},
{
"id": "2",
"entityType": "floor",
"status": "FAILED",
"url": null,
"createdOn": "2019-08-19T16:46:13Z"
},
{
"id": "3",
"entityType": "apartment",
"status": "SUCCESS",
"url": null,
"createdOn": "2019-08-19T16:46:13Z"
}
]
I tried out this solution [Parsing a dictionary to retrieve a key in Python 3.6
testStatusList= json.loads(status_response['Payload'].read())
body = testStatusList['body']
status =[]
for b in body:
for k,v in b.items():
if k == 'status':
status.append(v)
but I keep getting AttributeError: 'unicode' object has no attribute 'items'. Is there a different method to get items for unicode objects?
So I basically want to retrieve all the statuses i.e., PROCESSING, FAILED AND SUCCESS so that I can put an 'if' condition to display appropriate messages when something failed for that particular "id". I am very unsure about my approach as I am totally new to Python. Any help would be much appreciated thanks!
body is still a (unicode) string in your top blob. Use json.loads again on that string:
body = """[
{
"id": "1",
"entityType": "zone",
"status": "PROCESSING",
"url": null,
"createdOn": "2019-03-07T12:47:10Z"
},
{
"id": "2",
"entityType": "floor",
"status": "FAILED",
"url": null,
"createdOn": "2019-08-19T16:46:13Z"
},
{
"id": "3",
"entityType": "apartment",
"status": "SUCCESS",
"url": null,
"createdOn": "2019-08-19T16:46:13Z"
}
]"""
import json
body = json.loads(body)
status =[]
for b in body:
for k,v in b.items():
if k == 'status':
status.append(v)
print(status)
Result:
['PROCESSING', 'FAILED', 'SUCCESS']

to an XML file or RDF in python code. I didn't find posts about rdf so I tried for XML. I tried also to change the list to dict like in this post:
Python Json loads() returning string instead of dictionary?
but it is not working. In views.py I have:
fileroot = '[{"patient_id":"'+record_id+'"},'+content0+','+content1+','+content2+']'
jsonData = simplejson.loads(fileroot)
It returns 'list' object has no attribute 'items'. And if I change it to :
fileroot = '[{"patient_id":"'+record_id+'"},'+content0+','+content1+','+content2+']'
jsonData = simplejson.loads(fileroot)[0]
It returns nothing.
I also tried from this link:
https://www.safaribooksonline.com/library/view/python-cookbook-3rd/9781449357337/ch06s05.html
but it is not working again.
This will tranlsate your json object to xml

Where I am running into issues is in the "custom_fields" section specifically. I have a particular custom field inside of each ticket I need the value for, and I only want that particular value.
To spare you too many specifics of the Python code, I am reading through each value below for each ticket and adding it to an output variable before writing that output variable to a .csv. Here is the particular place the breakage is occuring:
output += str(ticket['custom_fields'][id:23825198]).replace(',', '')+','
All the replace nonsense is to make sure that since it is going into a comma delimited file, any commas inside of the values are removed. Anyway, here is the error I am getting:
output += str(ticket['custom_fields'][id:int(23825198)]).replace(',', '')+','
TypeError: slice indices must be integers or None or have an __index__ method
As you can see I have tried a couple different variations of this to try and resolve the issue, and have yet to find a fix. I could use some help!
Thanks...
Are you using json.loads()? If so you can then get the keys, and do an if statement against the keys. An example on how to get the keys and their respective values is shown below.
import json
some_json = """{
"id": 35436,
"url": "https://company.zendesk.com/api/v2/tickets/35436.json",
"external_id": "ahg35h3jh",

# load the json object
zenJSONObj = json.loads(some_json)
# Shows a list of all custom fields
print("All the custom field data")
print(zenJSONObj['custom_fields'])
print("----")
# Tells you all the keys in the custom_fields
print("How keys and the values")
for custom_field in zenJSONObj['custom_fields']:
print("----")
for key in custom_field.keys():
print("key:",key," value: ",custom_field[key])
You can then modify the JSON object by doing something like
print(zenJSONObj['custom_fields'][0])
zenJSONObj['custom_fields'][0]['value'] = 'something new'
print(zenJSONObj['custom_fields'][0])
Then re-encode it using the following:
newJSONObject = json.dumps(zenJSONObj, sort_keys=True, indent=4)
I hope this is of some help.
