            'editor-version': 'Neovim/0.6.1',

        }, data='{"client_id":"Iv1.b507a08c87ecfe98","scope":"read:user"}')


    # Parse the response json, isolating the device_code, user_code, and verification_uri
    resp_json = resp.json()
    device_code = resp_json.get('device_code')
    user_code = resp_json.get('user_code')
    verification_uri = resp_json.get('verification_uri')

    # Print the user code and verification uri
    print(f'Please visit {verification_uri} and enter code {user_code} to authenticate.')


    while True:
        time.sleep(5)
        resp = requests.post('https://github.com/login/oauth/access_token', headers={
            'accept': 'application/json',

        # Parse the response json, isolating the access_token
        resp_json = resp.json()
        access_token = resp_json.get('access_token')

        if access_token:
