A great majority of your many questions in this forum are already
answered in the available documentation online. You seem to leap
immediately to asking here rather than demonstrating that you have first
tried and failed to find answers in existing documentation.

You would save yourself a lot of time, not to mention social capital, if
you would invest the effort to learn how to research your answers at
<URL:http://docs.python.org/> and <URL:http://www.python.org/dev/>.
