将python脚本输出转换为csv

Question

我有一个小程序，它从数据库Yay返回某些用户位置的结果。我想将这些结果分别放在CSV中各自的列中。你将如何构建，以便csv读取IP，国家，城市......

import pygeoip
import csv

def ipLocator(ip):
    with open('ips.csv', 'wb') as csvfile:
         writer = csv.writer(csvfile)
         GeoIPDatabase = 'GeoLiteCity.dat'
         ipData = pygeoip.GeoIP(GeoIPDatabase)
         record = ipData.record_by_name(ip)
         try:
            print("%s" % ip)
            print("%s, %s, %s" % (record['city'], record['region_code'], record['country_name']))
            print("%s" % (record['metro_code']))
         except:
            print("Failed %s" % ip) 

def ip():
    with open('ipaddresses.csv') as csvfile:
        readCSV = csv.reader(csvfile, delimiter=',')
        print readCSV
        for row in readCSV:
            print ipLocator(row[0])

        with open('test.csv', 'wb') as fp:
            a = csv.writer(fp, delimiter=',')
            data = [['city'],['region_code'],['country_name']]
            a.writerows(data)


ip()

更新

import pygeoip
import csv
import os

def ipLocator(ip):
        GeoIPDatabase = 'GeoLiteCity.dat'
        ipData = pygeoip.GeoIP(GeoIPDatabase)
        record = ipData.record_by_name(ip)
        try:
            print("%s" % ip)
            print("%s, %s, %s" % (record['city'],    record['region_code'], record['country_name']))
            print("%s" % (record['metro_code']))
        except:
            print("Failed %s" % ip) 
def ip():
    with open('ipaddresses.csv') as csvfile:
        readCSV = csv.reader(csvfile, delimiter=',')
        print readCSV
        for row in readCSV:
            print ipLocator(row[0])

        with open('output.csv', 'wb') as outfile:
            csv_writer = csv.writer(outfile, delimiter=',')
            csv_writer.writerows(row[0])

ip()

这将返回垂直打印的批次的最后一个ipaddress，占据csv第一列的第一列：

1. 7
2. 4
4. 2
5. 0
6. 3

这不是我追求的目标
