Can't decode correctly JSON URL from Python

Question

I want to read some data from a JSON url, however, with my code i don't get a JSON structure, instead i get a string undecoded.

I've also tried reading the data directly from the url using pandas read_json , but i get this error message: UnicodeDecodeError: 'charmap' codec can't decode byte 0x81 in position 136430: character maps to <undefined> .

This is the main code i'm using:

from urllib.request import urlopen
import json

response = urlopen("https://data.nasa.gov/resource/y77d-th95.json")
json_data = response.read().decode('utf8','replace')

And this is what i get in json_data :

Any idea what i'm doing wrong?

Answer 1

trying to use json.loads directly on the result of read with default decode gives me a valid list,

try this please:

from urllib.request import urlopen
import json

response = urlopen("https://data.nasa.gov/resource/y77d-th95.json")
json_data = json.loads(response.read().decode())

print(json_data)
