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:

maps.google.co.ukdoes resolve, and if they are from Google really. Then your Python code may be using a proxy even if Chrome is not using one. Also did you try with any other name? Does the result change if you change the network to which your computer is attached to? – Patrick Mevzek
