我正在使用 Reliance Broadband，它具有基于 Web 的登录方式来访问互联网。它每 24 小时注销一次，所以我必须重新登录。

我遇到了一个PYTHON 脚本，它不断检查连接并保持连接有效。

不知何故，当我在安装最新的 Python 版本后在 Windows 上运行它时，出现以下语法错误。

C:\Documents and Settings\CS\Desktop>reliance-login.py

  File "C:\Documents and Settings\CS\Desktop\reliance-login.py", line 48
    if debug: print "Testing"
                            ^
SyntaxError: invalid syntax

谁能检查一下，让我知道到底是什么问题？

感谢 sr2222，我尝试了 2to3，删除所有 + n - 后...我仍然遇到一些错误。

以下是 2to3 之后的脚本。请您在您的机器上运行它n 帮助修复错误。

你下载的是 Python 2 还是 Python 3？那是 Python 2.X 打印语法，如果你有 Python 3 解释器，你会看到那个错误。该脚本可能是用 Python 2.X 编写的。您可以下载不同的解释器或在您的保持活动脚本的源上运行 2to3.py 脚本，以使其在 Python 3 下工作。

另外，哇，还有 ISP 仍然这样做吗？对不起，你被困住了。
