Hi Kishra, In the words of the old joke(*) why not just 'get out and get back in' and see if that fixes it? In other words I'd try a reinstall of Python, it looks like something has gone missing or got corrupted...
Alan G. (*)Three guys are in a car that breaks down. The first says "I'm an Electrical Engineer, I bet it's the electrics", jumps out and starts checking the wiring. The second guy says "I'm a mechanical engineer, it's probably the engine" and gets out to check the gaskets. The third guy says "I'm a software engineer, why don't we just get out of the car then get back in and see if that fixes it?" _______________________________________________ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
