无法写入CSV档案，Python

Question

这是我的代码，我向indexerror添加了异常，但未将其写入csv文件。

import urllib2
import csv
import time
import requests
import os

#a = open(r"C:\Drive F data\Client\Blake\III\2.txt")
a = ['http://www.houzz.com/trk/aHR0cDovL3d3dy5SSUtCLmNvbQ/b020157b98711b4a190eee3331eb0066/ue/MjA5ODg2MQ/1b9b00b9fdc9f270f14688046ef161e2',

with open("C:\Drive F data\Blake\III/2.csv", "ab")as export:
    names = ['source','link']
    writer = csv.DictWriter(export, fieldnames=names)
    writer.writeheader()
    for each in a:
        try:
            link = urllib2.urlopen(each).geturl()
        except IndexError:
            pass
        print each, link
        writer.writerow({'source':each,'link':link})

删除try＆exception后，它可以正常工作

Answer 1

我认为您在文件路径中缺少转义符。 "C:\\\\Drive F data\\\\Blake\\\\III\\\\2.csv"
