This is how I've been getting the country name for one IP address at a time, but I need to be able to do multiple, sometimes over 50 at a time.
>>>import geoip2.database
>>>
>>>reader = geoip2.database.Reader('/path/to/GeoLite2-City.mmdb')
>>>
>>>response = reader.city('128.101.101.101')
>>>
>>>response.country.iso_code
>>>
>>>response.country.name
