我在python3.3中编写了一个脚本来同步windows上的两个目录，效果很好；后来我想让它成为一个可执行文件，所以我把它移植到了 python 2.7（cx_freeze 给了我“找不到模块”错误）。不过，我遇到了一个奇怪的问题，即每当我输入程序的文件路径时，它都会给我一个错误；例如，如果我输入“C:\Users\Me\SourceDir”，程序就会中断，输出
File "<string>", line 1
C:\Users\Me\SourceDir
^
Syntax Error: Invalid Syntax
我很困惑为什么会这样。该程序在 python3.3 下运行良好（我应该添加相同的路径），这让我相信 2.7 在幕后发生了一些奇怪的事情。
谁能向我解释为什么会发生这种情况以及如何解决？
这也是程序的来源，虽然我觉得这并不重要
