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.

Regards,
\- Tal Einat
