Help on built-in function open in module nt:
 
open(path, flags, mode=511, *, dir_fd=None)
  Open a file for low level IO. Returns a file descriptor (integer).
 
  If dir_fd is not None, it should be a file descriptor open to a directory,
   and path should be relative; path will then be relative to that directory.
  dir_fd may not be implemented on your platform.
   If it is unavailable, using it will raise a NotImplementedError.
