【问题描述】：

当使用 NOminatim 和 GeoPy 对给定的地址字符串进行编码时，如何获取国家信息？

是否有任何结构化的方法可以在输出中获取国家/地区名称？一种方法是在最后一个“，”之后使用字符串来获取国家/地区，但这似乎不是一种可靠的方法。

from geopy.geocoders import Nominatim
geolocator = Nominatim(user_agent='myapplication')
x = 'PA - Cranberry Township'
location = geolocator.geocode(x, exactly_one=True,language="english", namedetails=True)
# how to get country name from response
location.raw

【问题讨论】：

为什么用逗号分割 display_name 并从中获取任何你需要的东西不健壮？
我不确定最后一个字符串是否总是国家

【解决方案1】：

给你：

from geopy.geocoders import Nominatim
geolocator = Nominatim(user_agent='myapplication')
x = 'PA - Cranberry Township'
location = geolocator.geocode(x, exactly_one=True,language="english", namedetails=True, addressdetails=True)
print(location.raw)
print(f"""Country Name: {location.raw['address']['country']}""")

输出：
