try 块中执行可能出错的文件读取,若文件不存在则触发 FileNotFoundError 异常并输出相应提示,权限不足则触发 PermissionError 异常并输出信息,无论是否发生异常,finally 块都会执行,确保输出 “操作完成”,保障程序的健壮性,避免因异常而崩溃。总之,这种结构能精准定位问题,避免程序崩溃。
从上面的输出可以看出,当前的PYTHONHOME值是(not set),即未设置。 在Windows系统中,可以通过以下命令来查看当前的PYTHONHOME值: C:\>echo%PYTHONHOME%(notset) 1. 2. 同样地,当前的PYTHONHOME值也是(not set)。 什么是PYTHONPATH? PYTHONPATH是一个Python搜索路径的环境变量。它告诉Python解释器在哪里搜索模块文...
