importos.path os.path.isfile(fname) 如果你要确定他是文件还是目录,从 Python 3.4 开始可以使用 pathlib 模块提供的面向对象的方法 (Python 2.7 为 pathlib2 模块): frompathlibimportPathmy_file=Path("/path/to/file")ifmy_file.is_file():# 指定的文件存在 检测是否为一个目录: ifmy_file.is_dir()...
Like theisfilemethod,os.path.isdiris the easiest way to check if a directory exists, or if the path given is a directory. importos os.path.isdir('./file.txt')# Falseos.path.isdir('./link.txt')# Falseos.path.isdir('./fake.txt')# Falseos.path.isdir('./dir')# Trueos.path.isdi...

>>> subprocess.check_output( 'dir non_existent_dir | exit 0', stderr=subprocess.STDOUT, universal_newlines=True, shell=True) '找不到文件\n' 注意:针对该函数,不要使用stderr=PIPE。因为不是从当前进程中读取管道(pipe),如果子进程没有生成足够的输出来填充OS的管道缓冲区,可能会阻塞子进程。
