Usage

Here is a function using geopy that takes a location as input and returns the ISO country code of the location: 

from geopy.geocoders import Nominatim

def get_country_code(location):
    geolocator = Nominatim(user_agent="my-application")
    try:
        location = geolocator.geocode(location)
        return location.raw['address']['country_code']
    except:
        return None

Not working with all locations - [address] is missing in .raw.

Workaround: combine geopy with pycountry Python library: pycountry to get latitude and longitude of a location and then use the latitude and longitude to get the ISO country code.

Also not working well.

At least, this function works - getting country name from location: 

from geopy.geocoders import Nominatim

def country_name_by_location(location):
    try:
        geolocator = Nominatim(user_agent='myapplication')
        location = geolocator.geocode(location)
        loc_data = (location.raw["display_name"])
        infos = loc_data.split(",")

        final_val = infos[-1]
        print(f"{final_val=}")
        return final_val
    except:
        return None

TODO - get country code from country name.
