Unless you are using an ancient piece of hardware -- a terminal is a 
pseudo terminal and a key stroke isn't a kernel event at all.

If you were looking for examples of kernel level functions you might 
want to consider driver interfaces -- how to program device interfaces 
-- that, too, can be done in Python -- but, again, you are always 
calling some underlying C function exposed via SWIG or another cross 
compilation tool.  Python doesn't reinvent system calls!  :-)
