Geolocate A City Or Country
This tutorial creates a function that attempts to take a city and country and return its latitude and longitude. But when the city is unavailable (which is often be the case), the returns the latitude and longitude of the center of the country.
from geopy.geocoders import Nominatim geolocator = Nominatim() import numpy as np
Create Geolocation Function
def geolocate(city=None, country=None): ''' Inputs city and country, or just country. Returns the lat/long coordinates of either the city if possible, if not, then returns lat/long of the center of the country. ''' /* If the city exists, */ if city != None: /* Try */ try: /* To geolocate the city and country */ loc = geolocator.geocode(str(city + ',' + country)) /* And return latitude and longitude */ return (loc.latitude, loc.longitude) /* Otherwise */ except: /* Return missing value */ return np.nan /* If the city doesn't exist */ else: /* Try */ try: /* Geolocate the center of the country */ loc = geolocator.geocode(country) /* And return latitude and longitude */ return (loc.latitude, loc.longitude) /* Otherwise*/ except: /* Return missing value */ return np.nan
Geolocate A City And Country
/* Geolocate a city and country */ geolocate(city='Austin', country='USA')
Geolocate Just A Country
/* Geolocate just a country */ geolocate(country='USA')

Two Machine Learning Fields
There are two sides to machine learning:
- Practical Machine Learning:This is about querying databases, cleaning data, writing scripts to transform data and gluing algorithm and libraries together and writing custom code to squeeze reliable answers from data to satisfy difficult and ill defined questions. It’s the mess of reality.
- Theoretical Machine Learning: This is about math and abstraction and idealized scenarios and limits and beauty and informing what is possible. It is a whole lot neater and cleaner and removed from the mess of reality.
