Task

Rename:

   a file called     input.txt     into     output.txt     and 
   a directory called     docs     into     mydocs.


This should be done twice:  
once "here", i.e. in the current working directory and once in the filesystem root.

It can be assumed that the user has the rights to do so.

(In unix-type systems, only the user root would have
sufficient permissions in the filesystem root.)




import os
 
os.rename("input.txt", "output.txt")
os.rename("docs", "mydocs")
 
os.rename(os.sep + "input.txt", os.sep + "output.txt")
os.rename(os.sep + "docs", os.sep + "mydocs")
