os.path.islink(xxx): Determine if xxx is a link

os.path. samplefile (a,b): Determine whether a b is the same file

os.path.normpath ('/tmp/a//b/'): canonical path form, this example returns/tmp/a/b

os.path.walk ('/tmp'): Recursive tree directory

os.path.getatime(): Get file or directory access time
