Run function for list of values

Question

I have created a function which grabs info about a coordinate using the OSM API. It works fine when there is only 1 lat and lng pair like below:

import pandas as pd
import urllib.request, json
radius = 1000

latitude = -33.8737909
longitude = 151.2055035

def get_results(latitude,longitude):
    overpass_url = "http://overpass-api.de/api/interpreter"
    overpass_query = '\n[out:json];\n(node["public_transport"](around:{0},{1},{2});\n way["public_transport"](around:{0},{1},{2});\n rel["public_transport"](around:{0},{1},{2});\n);\nout center;\n'.format(radius,latitude,longitude)
    response = requests.get(overpass_url,params={'data': overpass_query})
    data = response.json()
    output = {
        "public_transport":[tags['tags'].get('name') for tags in data['elements']]
    }
    return output

results =[]

for address in addresses:
    geocode_result = get_results(latitude,longitude)

results.append(geocode_result)
print(results)

The problem arises when I need to run the above code for multiple lat and lng pairs and append all the results together. For the sake of simplicity, let's say I have a list of two pairs of lat and lng values:

latitude = [-33.8737909, 47.36865]
longitude = [151.2055035, 8.539182]

The function I wrote no longer works. I'm baffled as to why, I suspect it has to do with how I've listed the lng and lat values? Perhaps something else?

Any help appreciated.

And why don't you loop through your lat/lng lists and call your function with each pair? — Mr. T, Jul 21 '18 at 10:23
ah my mistake! I had adapted the above code from a reverse geocoding code I had use previously. This might be the problem — AToe, Jul 21 '18 at 10:28
snakecharmerb's - zip as suggested in your link dd the trick. — AToe, Jul 21 '18 at 10:36
