使用谷歌地图在Python中进行地理编码

我刚写的这些代码有几个问题。代码如下：-

from googlemaps import GoogleMaps
import urllib, json
import csv

def geocode(addr):
url = "http://maps.googleapis.com/maps/api/geocode/json?address=%s&sensor=false" %    (urllib.quote(addr.replace(' ', '+')))
data = urllib.urlopen(url).read()
info = json.loads(data).get("results")[0].get("geometry").get("location")

return info

with open('addtest.csv', 'rb') as f:
reader = csv.reader(f)
for row in reader:
    row_count = sum(1 for row in reader)
    for i in range(0, row_count):
        r = geocode(row[i])
        print ("%s %s" % (r['lat'], r['lng']))
        csv_out = open('addtest_c.csv', 'wb')
        mywriter = csv.writer(csv_out)
        mywriter.writerows("%s %s" % (r['lat'], r['lng']))

我要做的是获取地址（一行一行），对其进行地理编码，并将坐标写入另一个csv文件中。如果未找到该位置的坐标，则脚本将在输出csv文件中写入“未找到”

我尝试了上面的脚本，但输出结果如下：-

1,.,8,4,9,4,4,2, ,1,0,2,.,9,2,8,8,3,4,1

我的测试文件（名为addtest.csv）中有12行，示例如下：-

Kg Sg Nibong,Lubuk,Semerah,Parit Sulong,Batu Pahat,Johor
Kg Parit Bentong,Spg Kiri,Sri Medan,Parit Sulong,Batu Pahat,Johor
Ldg B-1, Yong Peng,Tg Semberong,Yong Peng,Ayer Hitam,Batu Pahat,Johor
Kg Sri Belahan,Sg Kluang,Rengit,Batu Pahat,Batu Pahat,Johor
Parit Besar,Bagan,Semerah,Parit Sulong,Batu Pahat,Johor
Spg Tiga Bagan,Bagan,Semerah,Parit Sulong,Batu Pahat,Johor
Parit Besar,Bagan,Semerah,Parit Sulong,Batu Pahat,Johor
Parit Selulon,Linau,Parit Yaani,Sri Gading,Batu Pahat,Johor
Parit Khalil,Sri Gading,Semarang,Ayer Hitam,Batu Pahat,Johor
Kg Parit Dalam,Sri Medan,Sri Medan,Parit Sulong,Batu Pahat,Johor
Kg Parit Jatuh,Tg Semberong,Yong Peng,Ayer Hitam,Batu Pahat,Johor
Parit Orang Kaya,Bagan,Semerah,Parit Sulong,Batu Pahat,Johor

任何帮助都将不胜感激。如果您需要更多信息，请发表评论。我正在Windows上使用Python 2.7.8
