I think the problem is that you're binding a low-level file id to
sys.stdout instead of a file object. Try:

            sys.stdout = 
open("C://Users//lutfi//Documents//tezzzz//log.txt" , "a" )

Actually, changing sys.stdout just to use print a single string is a bad
idea. Try this instead:

           log_file = 
open("C://Users//lutfi//Documents//tezzzz//log.txt" , "a" )
           print >> log_file, "%d %s" %(k, attr.toString())
           log_file.close()
