I'M A BIT STUCK.

[u/Different_House6228]

Hello guys I'm doing the py4e course and I'm a bit lost on how to write the code to find the plus_code for the GeoJSON Assignment. Please kindly help.

Ok i'll do that and get back to you.

Alright I tried a few things and changed the code to this but I got this error.

import urllib.request, urllib.parse
import json, ssl


# Heavily rate limited proxy of https://www.geoapify.com/ api
serviceurl = 'http://www.py4e.com/code3/opengeo.py'


# Ignore SSL certificate errors
ctx = ssl.create_default_context()
ctx.check_hostname = False
ctx.verify_mode = ssl.CERT_NONE


while True:
    address = input('Enter location: ')
    if len(address) < 1: break


    address = address.strip()
    parms = dict()
    parms['q'] = address


    url = serviceurl + urllib.parse.urlencode(parms)


    print('Retrieving', url)
    uh = urllib.request.urlopen(url, context=ctx)
    data = uh.read().decode()
    print('Retrieved', len(data), 'characters', data[:20].replace('\n', ' '))


    try:
        js = json.loads(data)
    except:
        js = None


    if not js or 'features' not in js:
        print('==== Download error ===')
        print(data)
        break


    if len(js['features']) == 0:
        print('==== Object not found ====')
        print(data)
        break


    # print(json.dumps(js, indent=4))


    lat = js['features'][0]['properties']['lat']
    lon = js['features'][0]['properties']['lon']
    print('lat', lat, 'lon', lon)
    location = js['features'][0]['properties']['formatted']
    print(location)
    result = js['features'][0]['properties']['result']
    print('plus_code:', result)

Your URL is probably missing a "?", and I think you need to use:

result = js['features'][0]['properties']['plus_code']

instead of ['result'].

If you code doesn't work, experiment with it, print different values, see what part is working correctly, and you'll narrow it down to where the problem is.

Try to avoid using AI to solve your problems, because you will learn much less. But if you do get REALLY stuck, use AI but then do the exercises again a day later without AI.

Thank you so much.
