我使用谷歌的 API。

 from urllib2 import urlopen
import json
def getplace(lat, lon):
    url = "http://maps.googleapis.com/maps/api/geocode/json?"
    url += "latlng=%s,%s&sensor=false" % (lat, lon)
    v = urlopen(url).read()
    j = json.loads(v)
    components = j['results'][0]['address_components']
    country = town = None
    for c in components:
        if "country" in c['types']:
            country = c['long_name']
        if "postal_town" in c['types']:
            town = c['long_name']
    return town, country

print(getplace(51.1, 0.1))
print(getplace(51.2, 0.1))
print(getplace(51.3, 0.1))

输出：

 (u'Hartfield', u'United Kingdom')
(u'Edenbridge', u'United Kingdom')
(u'Sevenoaks', u'United Kingdom')

谷歌此后删除了对其 API 的无密钥访问。前往谷歌并注册一个密钥，您每天可以获得约 1,000 个免费查询。接受的答案中的代码应该像这样修改（不能添加评论，没有足够的代表）。

 from urllib.request import urlopen
import json

def getplace(lat, lon):
    key = "yourkeyhere"
    url = "https://maps.googleapis.com/maps/api/geocode/json?"
    url += "latlng=%s,%s&sensor=false&key=%s" % (lat, lon, key)
    v = urlopen(url).read()
    j = json.loads(v)
    components = j['results'][0]['address_components']
    country = town = None
    for c in components:
        if "country" in c['types']:
            country = c['long_name']
        if "postal_town" in c['types']:
            town = c['long_name']

    return town, country

print(getplace(51.1, 0.1))
print(getplace(51.2, 0.1))
print(getplace(51.3, 0.1))
