Python module for getting latitude and longitude from the name of a US city?

问题

I am looking for a python module which can take in the name of the city as the input and return the latitude and longitude of the input.

回答1:

Have a look at geopy. In the "getting started" documentation it shows:

>>> from geopy import geocoders  
>>> gn = geocoders.GeoNames()

>>> print gn.geocode("Cleveland, OH 44106")
(u'Cleveland, OH, US', (41.4994954, -81.6954088))

>>> gn.geocode("Cleveland, OH", exactly_one=False)[0]
(u'Cleveland, OH, US', (41.4994954, -81.6954088))

An example:

from geopy.geocoders import Nominatim
geolocator = Nominatim(user_agent='myapplication')
location = geolocator.geocode("Chicago Illinois")
print(location.address)

Available info:

>>> location.raw
{u'display_name': u'Chicago, Cook County, Illinois, United States of America', u
