What error is it giving you?
If you do exactly this:
data = json.loads('{"lat":444, "lon":555}')
Then:
data['lat']
SHOULD NOT give you any error at all.

October 20, 2023 -
Wondering if there’s a way to do this with the standard json module. Looking to just extract the value of 1 key from a large json file without needing to load the whole thing
For example, I had a json file with:
{
“x”: …,
“y”: …,
“z”: …
}is there a way of doing something like json.load(…) but only reading everything under key “y” for example?

Do you have any control over the structure of the JSON file? If so you could maybe consider JSON-Lines format, where each line is itself a separate JSON document. Then you would have to iterate through and parse each line, but you could stop when you found the one you want. I have no idea if that would be quicker overall though.

July 6, 2023 - After loading JSON data into Python, you can access specific data elements using the keys provided in the JSON structure. In JSON, data is typically stored in either an array or an object. To access data within a JSON array, you can use array indexing, while to access data within an object, you can use key-value pairs.

I have a JSON file that I want to automatically check specific values, like myJSON['generic']['lessgeneric']['store'] should be equal to 100,
was thinking of doing something like this:
checks = [ {'name':'field_1','path':'myJSON['generic']['lessgeneric']['store']','value':'100'} ]
but I have no clue how to convert the string "myJSON['generic']['lessgeneric']['store']" into it's value, any help would be appreciated!
edit: how I solved it
path = "generic>lessgeneric>store"
value = 100
def check_value(path,value):
temp_json = my_json
for key in path.split(">"):
temp_json = temp_json[key]
if temp_json == value:

I have an undesirable JSON object that I can't modify:
{
"programs": [
],
"streams": [
{
"index": 0,
"codec_name": "hevc",
"codec_type": "video"
},
{
"index": 1,
"codec_name": "aac",
"codec_type": "audio"
},
{
"index": 2,
"codec_name": "opus",
"codec_type": "audio"
},
{
"index": 3,
"codec_name": "ac3",
"codec_type": "audio"
},
{
"index": 4,
"codec_name": "ass",
"codec_type": "subtitle"
},
{
"index": 5,
"codec_name": "ttf",
"codec_type": "attachment"
}
]
}This is psudo json from the very real output of ffprobe -loglevel error -show_entries format:stream=index,stream,codec_type,codec_name -of json FILENAME
I need to get the first codec_name from the lowest index of the codec_type: audio.
In this case, index 1, 2, and 3 are all of codec_type: audio, so the lowest index/first instance would be 1 and my codec_name would be aac.
Any ideas on how to move forward on a problem like this? I can't seem to find any stackoverflow threads with anything similar.

JSON imported with the JSON package is actually a Python dictionary and thus can be treated like any other dictionary. If the indexes are always in order you can just iterate through the streams and for the first one where the codec type is audio you can just return the codec name: def get_first_audio_codec(dictionary: dict) -> str: for stream in dictionary['streams']: if stream['codec_type'] == 'audio': return stream['codec_name'] first_audio_codec = get_first_audio_codec(dictionary) print(first_audio_codec) Output: aac

You are getting that error because you cannot treat JSON as a dictionary yet, you must load it first
import json
response = json.loads(JSON_RESPONSE)
all_C_values = [dic['c'] for dic in response]

Try this:
D = [ { "a": 3, "b": 2, "c": 1, }, { "a": 3, "b": 2, "c": 1 } ]
x = [x['c'] for x in D]
print(x)

Beyond basic parsing, you'll often need to handle nested structures, validate data integrity, manage, and transform data formats. This guide covers practical JSON parsing techniques you can use in your projects right away. Let’s get started! ... JSON represents data using a simple syntax with six data types: objects (key-value pairs), arrays, strings, numbers, Booleans, and null.
