Saving a json file to computer python

You can do it just as you would without requests. Your code might look something like,

import json
import requests

solditems = requests.get('https://github.com/timeline.json') # (your url)
data = solditems.json()
with open('data.json', 'w') as f:
    json.dump(data, f)

This is also very easy with the standard library's new pathlib library. Do note that this code is purely "writing the bytes of an HTTP response to a file". It's fast, but it does no validation that the bytes you're writing are valid JSON.

import requests
import pathlib

solditems = requests.get('https://github.com/timeline.json') # (your url)
pathlib.Path('data.json').write_bytes(solditems.content)
