我试图使用pandas确定geopy数据框中每一行的国家名。我所拥有的是：
import pandas as pd
from geopy.geocoders import GoogleV3
df = pd.DataFrame({'ser_no': [1, 1, 1, 2, 2, 2],
'lat': [53.57, 35.52, 35.53, 54.66, 54.67, 55.8],
'lon': [-117.20, -98.29, -98.32, -119.48, -119.47, -119.46]})
def get_country(locations):
locations = geolocator.reverse(row['lat'], row['lon'], timeout = 10)
for location in locations:
for component in location.raw['address_components']:
if 'country' in component['types']:
return component['long_name']
my_key = my_api_key
geolocator = GoogleV3(my_key, proxies ={"http": 'my proxy',
"https": 'my proxy'})
df['country'] = df.apply(lambda row: get_country(row), axis = 1)
这又回来了
lat lon ser_no country
0 53.57 -117.20 1 <function get_country at 0x000000000F6F9C88>
1 35.52 -98.29 1 <function get_country at 0x000000000F6F9C88>
2 35.53 -98.32 1 <function get_country at 0x000000000F6F9C88>
3 54.66 -119.48 2 <function get_country at 0x000000000F6F9C88>
4 54.67 -119.47 2 <function get_country at 0x000000000F6F9C88>
5 55.80 -119.46 2 <function get_country at 0x000000000F6F9C88>
没有发生任何错误，但我的输出没有用处。我不确定它是否返回错误，或者我的
apply中是否有错误。 最佳答案
geolocator.reverse获取一个字符串，因此需要将函数更改为：
def get_country(row):
pos = str(row['lat']) + ', ' + str(row['lon'])
locations = geolocator.reverse(pos, timeout = 10)
#... rest of func the same
