For creating temporary files and directories see the tempfile module, and for high-level file and directory handling see the shutil module. The design of all built-in operating system dependent modules of Python is such that as long as the same functionality is available, it uses the same interface; for example, the function os. Extensions peculiar to a particular operating system are also available through the os module, but using them is of course a threat to portability. All functions accepting path or file names accept both bytes and string objects, and result in an object of the same type, if a path or file name is returned.
