如何让Google AdWords API Python客户端库工作？
有没有人知道最新的教程，教怎么使用Python的AdWords客户端？如果没有，谁能帮我看看我遇到的问题？我是不是配置错了，或者说Python 2.6不被支持？
在我的Windows上，我安装了：
- Python 2.6
- setuptools-0.6c11.win32-py2.6.exe
- PyXML-0.8.4
- SOAPpy-0.12.4
- ZSI-2.0-rc3
- adwords_api_python_13.2.0
我在AdWords配置程序里填了MCC账户的邮箱、密码、空白的客户邮箱和ID，还有开发者令牌用的是同一个邮箱加上“+USD”。
现在，如果我用SOAPpy作为SOAP库，就会出现一个异常，提示有一个意外的关键字参数timeout，这个参数是SOAPpy里的一个函数传给另一个函数的。
如果我用ZSI作为SOAP库（我觉得这个是更推荐的），我就会遇到以下异常：

后面还有一些XML，我已经修改过，去掉了识别信息：

我的代码如下：
from adspygoogle.adwords.AdWordsClient import AdWordsClient
from adspygoogle.common import Utils
client = AdWordsClient(path = '../../installers/adwords_api_python_13.2.0.tar/adwords_api_python_13.2.0')
campaign_service = client.GetCampaignService('https://adwords-sandbox.google.com', 'v201008')
operations = [{
'operator': 'ADD',
'operand': {
'name': 'Interplanetary Cruise #%s' % Utils.GetUniqueName(),
'status': 'PAUSED',
'biddingStrategy': {
'type': 'ManualCPC'
},
'endDate': '20120101',
'budget': {
'period': 'DAILY',
'amount': {
'microAmount': '50000000'
},
'deliveryMethod': 'STANDARD'
}
}
}]
campaigns = campaign_service.Mutate(operations)[0]
# Display results.
for campaign in campaigns['value']:
print ('Campaign with name \'%s\' and id \'%s\' was added.'
% (campaign['name'], campaign['id']))
print
print ('Usage: %s units, %s operations' % (client.GetUnits(),
client.GetOperations()))
需要注意的是，教程里的代码在http://code.google.com/apis/adwords/docs/tutorial.html根本不管用，当前版本的客户端里根本没有aw_api.Client这个东西。不过上面的代码大部分是从教程里复制过来的。
客户端提供的示例代码也出现了同样的错误。
如果当前的客户端库有问题，我可以试试旧版的，虽然如果有区别的话，我需要一个支持TargetingIdeaService的库。
[编辑：哦，抱歉，我忘了说我其实编辑过AdWords客户端的代码。在Utils.GetDataFromCsvFile里，我把构造传给urllib.urlopen的文件URL的那行中的.replace(':','|')去掉了。
这让我怀疑我的Python版本可能不被支持，因为Windows上的Python 2.6似乎无法打开这个URL file:///c|/foo/bar/baz/]
