Yes. Use curses on Unix or msvcrt on windows

Example of latter on my online tutor in the event handling topic.

That depends on what you are using. If its a paper based teletype 
then you can change the background colour by changing the paper!
If its a vt100 series terminal you can use the DEC  escape codes.
If its a DOS window then you an use ANSI codes provided ANSI.SYS
is loaded.

The point is that Python doesn't know what kind of terminal you 
are using so doesn't know how to change it. These things are not
standardised.
