Mac环境下Python目录同步程序终端运行无法访问目录问题排查

我编写了一个用于同步源文件目录的Python程序，该程序支持接收命令行参数或用户输入的目录路径。在VS Code中运行时，程序可正常访问目录（示例输入：/Users/dennis/Desktop/Phonenix Enigma Distro），但在Mac终端运行时无法找到指定目录。程序代码位于/Users/dennis/Documents/Python/Projects/Python backup software路径下，以下是获取并验证目录参数的代码片段。作为Python新手，我想排查问题原因：是否需要先设置工作目录为根目录？还是我输入目录的方式有误？
