Sorry ChrisA,not only him for all, for the mess i have created.It was the first time for me on google groups. 
I am very happy to inform all of you that the problem is solved. The problem was due to the prescence of duplicates for genericpath.pyc and stat.pyc.I have deleted them and new ones were generated as i started python.
Thanking all of you for assisting me in solving the issue.
