Hi to all
python now has grown to a versatile language that can
accomplish tasks for many different purposes. However,
AFAIK, little is known about its ability of kernel coding.
So I am wondering if python can do some kernel coding that
used to be the private garden of C/C++. For example, can python
intercept the input of keyboard on a system level? someone told me
it's a kernel thing, isn't it?
http://wiki.python.org/moin/elmer
well, straightly speaking, how can I know a key is pressed on a system-
level if
using python?
What has that todo with kernel programming? You can use e.g. pygame to
get keystrokes. Or under linux, read (if you are root) the keyboard
input file - I've done that to support several keyboards attached to a
machine.
And the original question: no, python can't be used as kernel
programming language. Amongst other reasons, performance & the GIL
prevent that.

Of course you can code kernel routines in Python -- you are just calling
the underlying C interface. The GIL means you have to manage
threadsafety on your own -- it doesn't imply kernel programming can not
be done.
I'm not talking about writing an OS in Python (though a simple DOS-like
OS is very possible). Nor would I suggest writing device drivers in
Python -- but of course you can call kernel routines and manage some
kernel resources effectively. Python's IPC libraries expose kernel
functionality.
