how to can loop through an array of array in a json object in python

https://github.com/Asabeneh/30-Days-Of-Python/blob/ff24ab221faaec455b664ad5bbdc6e0de76c3caf/data/countries_data.json
how can i loop through this countries_data.json file (see link above) to get 'languages'
i have tried:
import json
f = open("countries_data.json")
file = f.read()
# print(file)
for item in file:
print(item)

You have everything correct and set up but you didn't load the json file. Also there is a double space on "f = open". You also didn't open the file with the read parameter, not too sure if its needed though.
Correct code:
import json
f = open("countries_data.json", "r")
file = json.loads(f.read())
for item in file:
print(item)
Hope this helped, always double check your code.

You can see that you import the json module at the beginning, so you might as well use it
If you go to the documentation you will see a function allowing you to read this file directly.
In the end you end up with just a dictionary list, the code can be summarized as follows.
import json
with open("test/countries_data.json") as file:
data = json.load(file)
for item in data:
print(item["languages"])

You are missing one essential step, which is parsing the JSON data to Python datastructures.
import json
# read file
f = open("countries.json")
# parse JSON to Python datastructures
countries = json.load(f)
# now you have a list of countries
print(type(countries))
# loop through list of countries
for country in countries:
# you can access languages with country["languages"]; JSON objects are Python dictionaries now
print(type(country))
for language in country["languages"]:
print(language)
f.close()
Expected output:
<class 'list'>
<class 'dict'>
Pashto
Uzbek
Turkmen
...

You can use the json built-in package to deserialize the content of that file.
A sample of usage
data = """[
{
"name": "Afghanistan",
"capital": "Kabul",
"languages": [
"Pashto",
"Uzbek",
"Turkmen"
],
"population": 27657145,
"flag": "https://restcountries.eu/data/afg.svg",
"currency": "Afghan afghani"
},
{
"name": "Åland Islands",
"capital": "Mariehamn",
"languages": [
"Swedish"
],
"population": 28875,
"flag": "https://restcountries.eu/data/ala.svg",
"currency": "Euro"
}]"""
# deserializing
print(json.loads(data))
For more complex content have a look to the JSONDecoder.

EDIT:
import json
path = # my file
with open(path, 'r') as fd:
# iterate over the dictionaries
for d in json.loads(fd.read()):
print(d['languages'])
EDIT: extra - top 10 languages
import json
import itertools as it
path = # path to file
with open(path, 'r') as fd:
text = fd.read()
languages_from_file = list(it.chain(*(d['languages'] for d in json.loads(text))))
# get unique "list" of languages
languages_all = set(languages_from_file)
# count the repeated languages
languages_count = {l: languages_from_file.count(l) for l in languages_all}
# order them per descending value
top_ten_languages = sorted(languages_count.items(), key=lambda k: k[1], reverse=True)[:10]
print(top_ten_languages)

Modify a sub value of json file using python

I'm trying to create multiple JSON files with different numbers at specific value, this is my code :
import json
json_dict = {
"assetName": "GhostCastle#",
"previewImageNft": {
"mime_Type": "png",
"description": "#",
"fileFromIPFS": "QmNuFreEoJy9CHhXchxaDAwuFXPHu84KYWY9U7S2banxFS/#.png",
"metadataPlaceholder": [
{
"": ""
}
]
}
}
n = 10
for i in range(1, n+1):
json_dict["assetName"] = f"GhostCastle{i}"
json_dict[#What to put here to choose "fileFromIPFS"] = f"QmNuFreEoJy9CHhXchxaDAwuFXPHu84KYWY9U7S2banxFS/{i}.png"
with open(f"{i}.json", 'w') as json_file:
#json.dump() method save dict json to file
json.dump(json_dict, json_file)
so What to put to choose "fileFromIPFS" in the second json_dict

Reading a json file that has multiple lines

I have a function that I apply to a json file. It works if it looks like this:
import json
def myfunction(dictionary):
#does things
return new_dictionary
data = """{
"_id": {
"$oid": "5e7511c45cb29ef48b8cfcff"
},
"description": "some text",
"startDate": {
"$date": "5e7511c45cb29ef48b8cfcff"
},
"completionDate": {
"$date": "2021-01-05T14:59:58.046Z"
},
"videos":[{"$oid":"5ecf6cc19ad2a4dfea993fed"}]
}"""
info = json.loads(data)
refined = key_replacer(info)
new_data = json.dumps(refined)
print(new_data)
However, I need to apply it to a whole while and the input looks like this (there are multiple elements and they are not separated by commas, they are one after another):
{"_id":{"$oid":"5f06cb272cfede51800b6b53"},"company":{"$oid":"5cdac819b6d0092cd6fb69d3"},"name":"SomeName","videos":[{"$oid":"5ecf6cc19ad2a4dfea993fed"}]}
{"_id":{"$oid":"5ddb781fb4a9862c5fbd298c"},"company":{"$oid":"5d22cf72262f0301ecacd706"},"name":"SomeName2","videos":[{"$oid":"5dd3f09727658a1b9b4fb5fd"},{"$oid":"5d78b5a536e59001a4357f4c"},{"$oid":"5de0b85e129ef7026f27ad47"}]}
How could I do this? I tried opening and reading the file, using load and dump instead of loads and dumps, and it still doesn't work. Do I need to read, or iterate over every line?

You are dealing with ndjson(Newline delimited JSON) data format.
You have to read the whole data string, split it by lines and parse each line as a JSON object resulting in a list of JSONs:
def parse_ndjson(data):
return [json.loads(l) for l in data.splitlines()]
with open('C:\\Users\\test.json', 'r', encoding="utf8") as handle:
data = handle.read()
dicts = parse_ndjson(data)
for d in dicts:
new_d = my_function(d)
print("New dict", new_d)

How can I export a dictionary inside a list that's already in a JSON file? | Python

I want to get the dictionary below inside my data array, couldn't find much on this as most tutorials show you how to chuck variable right into the json, without ordering it into an array or object.
the JSON:
#JSON file
{
"data" :
[
]
}
the python file I want to export from:
import json
#Python file
your_facebook_info = {'name':'johhny', 'age':213, 'money':'lots'}
desired outcome:
{
"data" :
[
your_facebook_info = {
'name':'johhny',
'age':213,
'money':'lots'
}
]
}

Try this. You read the file, append the new data, write that databack to the file.
import json
#Python file
your_facebook_info = {'name':'johhny', 'age':213, 'money':'lots'}
with open('text.json','r') as inputfile:
data = json.load(inputfile)
data['data'].append(your_facebook_info)
with open("text.json", "w") as outfile:
json.dump(data, outfile)

Python modify structure (to be accepted by BQ) of JSON with python and save it

I would like to ask if there is an easy way to modify JSON by using Python?
I have found some of the relevant topic- How to update json file with python But could not figure out the solution for my current issue.
Currently, JSON looks like this:
{
"X": [
{
"sample_topic_x":"sample_content_x_1",
...
}
{
"sample_topic_x":"sample_content_x_2",
...
}
......
]
"Y": [
{
"sample_topic_y":"sample_content_y_1",
...
}
{
"sample_topic_y":"sample_content_y_2",
...
}
......
]
}
Required: To be accepted by BQ / Need to remove "Y", keep only "X" in this format.
{"sample_topic_x":"sample_content_x_1",.....}
{"sample_topic_x":"sample_content_x_2",.....}
{"sample_topic_x":"sample_content_x_3",.....}
Any relevant documentation, topics?
P.S> Update 1.0
import json
json_path = 'C:\XXX\exportReport.json'
def updateJsonFile():
jsonFile = open(json_path, "r") # Open the JSON file for reading
data = json.load(jsonFile) # Read the JSON into the buffer
jsonFile.close() # Close the JSON file
updateJsonFile()

Solution:
import json
json_path = 'C:\XXX\exportReport.json'
output_path = 'C:\XXX\your_output_file.txt'
with open(json_path) as f:
data = json.loads(f.read())
# Opening output file in append mode
# Note: Output file is not JSON, as the required format is not valid json
with open(output_file, "a+") as op:
for element in data.get('X'):
op.write(json.dumps(element) + "\n")
Explanation:
Load the input json file using json.loads. The output file will be a plain text file and not a JSON file as the required output format is not a valid JSON. Use a .txt file for storing the output. Store value of json.loads() in data. To get inner element X which is a list of dictionaries, use data.get('X'), which will return list. Iterate over it and write json.dumps() to the output file, each element in a newline.
C:\XXX\exportReport.json
{
"X": [
{
"sample_topic_x":"sample_content_x_1",
...
}
{
"sample_topic_x":"sample_content_x_2",
...
}
......
]
"Y": [
{
"sample_topic_y":"sample_content_y_1",
...
}
{
"sample_topic_y":"sample_content_y_2",
...
}
......
]
}
C:\XXX\your_output_file.txt
{"sample_topic_x":"sample_content_x_1",.....}
{"sample_topic_x":"sample_content_x_2",.....}
{"sample_topic_x":"sample_content_x_3",.....}

You need extract parent data at first. And definite this to a variable. And search "X" data in this variable.
