I recently installed python 3.7 on macOS High OSierra and spent ages trying to get it working. That question is here. Currently I am having problems with the below code and wondered if anyone can help.
import geopy
geocoder = geopy.geocoders.GoogleV3(domain = "maps.google.co.uk")
geocoder.geocode("Cambridge", exactly_one = False)
Results in the following error:
