python - 使用 Geopy 获取多个位置的纬度和经度

Question

我一直在导入包含多个地址的 csv 数据集。我想获取这些地方的纬度和经度，并将它们与原始地址一起写入新的 csv 文件。我一直在尝试使用 python 中的 Geopy 来实现这一目标。下面给出的是代码:

import csv
##from time import sleep

from geopy.geocoders import Nominatim

with open('D:/location_to_lat_lon/tolocate.csv', 'r') as fp:

        with open('D:/location_to_lat_lon/places_located.csv', 'w',newline='') as op:
            a = csv.writer(op)
            a.writerow(["Town","District","State","Country","Address","Latitude","Longitude"])
            for line in fp.readlines():
                geolocator = Nominatim()
                town_new = line.split(',')[0]
                district_new = line.split(',')[1]
                state_new = line.split(',')[2]
                country_new = line.split(',')[3]
                address_new = line.split(',')[4]
                location = geolocator.geocode(address_new)
                lat=location.latitude
                lon=location.longitude
                ##time.sleep(3)
              a.writerow([town_new,district_new,state_new,country_new,address_new,lat,lon])

但是，每次运行此代码时都会出现以下错误

Traceback (most recent call last): File "", line 13, in lat=location.latitude AttributeError: 'NoneType' object has no attribute 'latitude

谁能帮我解决这个问题吗？

由于各种原因(包括地理编码服务没有给定地址的地理空间数据)，您有时会忘记位置有时可能为“无”。

简单做

location = geolocator.geocode(address_new)
if location:
    lat=location.latitude
    lon=location.longitude
else :
    lat = None
    long = None
