Hi Vincent,
It's possible that this information might already be in your environment.
If you're using the 'bash' shell, and if the 'checkwinsize' option is set
in bash, then bash should keep track of the window size through LINES and
COLUMNS. According to the "Art of Unix Programming":
http://www.faqs.org/docs/artu/ch10s04.html
those variables are fairly standard and lots of programs use them. But I
don't know if other shells go out of their way to maintain consistancy
with the current terminal size on terminal resizing.
If you want to get at the environment variables, take a look at the
'os.environ' dictionary:

Alternatively, if you're on Unix, the 'curses' module will get you the
information you want.

On Windows, it looks like you can use the following cookbook recipe:
