Python Mac-Can'；找不到文件

有人为我编写了Python代码，但没有意识到我在Mac上

我得到以下错误：

FileNotFoundError

在Python2.x中不存在；您确定使用的是Python 3吗？请阅读错误消息：

NameError:未定义全局名称“FileNotFoundError”

-它来自Python本身，不是找不到文件，而是全局命名空间中缺少名称。如上所述，您应该使用python3run

/usr/bin/pythonw-v运行此命令以查找Python版本，尽管Python只会在出现异常时尝试查找
FileNotFoundError
，所以一旦使用了正确的Python版本，这里可能仍然有一个问题。谢谢大家。看起来我正在运行V3.8。
