当我将http：// localhost：8888 / cgi-bin / peoplecgi.py？action = Fetch& key = sue(sue是货架上的有效密钥)发送到下面的cgi脚本时,我得到了以下内容(也是在使用Python 3.3的OSX上).任何想法出了什么问题？
127.0.0.1 - - [04/Feb/2014 10:38:41] "GET /cgi-bin/peoplecgi.py?action=Fetch&key=sue HTTP/1.1" 200 -

我正在研究O’Reilly的Programming Python 4th Edition.这是基于示例1-33的问题.

解决方法:
在这种情况下,解决方案是我使用了错误版本的Python运行脚本. osx 10.9中的默认值是Python 2.7.5.我想使用python 3.3来运行它,因此我的解决方案只是简单地使用适当的版本执行它：#！/usr/local/bin / python3
