Python包：根据地址获取国家/地区（非IP）

Question

I'm searching for python package that can help me get the country from the address.

I use pycountry but I could used only if I have the country in the address, but I don't know what to do if I have, for ex:

"Georgetown, TX" , "Santa Fe, New Mexico", "Nuremberg", "Haarbergstr. 67 D-99097 Erfurt".

I don't know what to do when I have no country in address, and no clear pattern.

Seems geopy can do it relatively easily. An example adopted from the documentation :

>>> import geopy   
>>> from geopy.geocoders import Nominatim   
>>> gl = Nominatim()   
>>> l = gl.geocode("Georgetown, TX")   
    # now we have l = Location((30.671598, -97.6550065012, 0.0))
>>> l.address
[u'Georgetown', u' Williamson County', u' Texas', u' United States of America']
# split that address on commas into a list, and get the last item (i.e. the country)
>>> l.address.split(',')[-1]
u' United States of America'

We got it! Now, test it on other locations

>>> l = gl.geocode("Santa Fe, New Mexico")
l.address.split(',')[-1]
u' United States of America'
>>> l = gl.geocode("Nuremberg")
>>> l.address.split(',')[-1]
u' Deutschland'
>>> l = gl.geocode("Haarbergstr. 67 D-99097 Erfurt")
>>> l.address.split(',')[-1]
u' Europe'

So you could automate the list in a script:

import geopy
from geopy.geocoders import Nominatim

geolocator = Nominatim()

list_of_locations = "Georgetown, TX" , "Santa Fe, New Mexico", "Nuremberg", "Haarbergstr. 67 D-99097 Erfurt"

for loc in list_of_locations:
    location = geolocator.geocode(loc)
    fulladdress = location.address
    country = fulladdress.split(',')[-1]
    print '{loc}: {country}'.format(loc=loc, country=country)

Output:

Georgetown, TX:  United States of America
Santa Fe, New Mexico:  United States of America
Nuremberg:  Deutschland
Haarbergstr. 67 D-99097 Erfurt:  Europe

Hope this helps.
