Hello Harish, The appropriate place to ask questions like this is python-list [1], or perhaps Stack Overflow. If you meant to suggest changing the behavior of Python in such cases, you should first discuss this on python-list, and then post a clearly written suggestion to python-ideas [2]. This list, python-dev, is used for discussing the development *of* the Python language. See the "Python Mailing Lists" page [3] for more information.
