File Path Processing
os.path.basename("/home/foo/Downloads/000000.pcd")gives the string after the last “/”. So here we get:000000.pcdos.path.splitext("/home/foo/Downloads/000000.pcd")gives'/home/foo/Downloads/000000', '.pcd'

p = Path('/home/halo_runtime/install/velodyne_msgs/share/velodyne_msgs/ros1_msg/VelodyneScan.msg')
p.name # 'VelodyneScan.msg' (base filename)
p.stem # 'VelodyneScan' (without extension)
p.suffix # '.msg' (extension)
p.suffixes # ['.msg'] (all extensions, useful for e.g. '.tar.gz')
