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? 20 6889

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

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! :-)

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.

I understood the OP's question as "can one program kernelspace routines

does that either.

OP: "I am wondering if python can do some kernel coding that

The answer is yes. IPC and py-pf are examples. If you don't think of
packet filtering as kernel coding, I can understand. But clearly the
Python interfaces to fork(), waitpid(), signal(), alarm() and so forth
are forays into the once private garden of C.

"kernel coding" is pretty clear I'd say - coding a or in the kernel. Not
coding that runs on an OS that happens to have a kernel.

Also not "kernel coding" in my book. system-near coding - yes. But not
coding a kernel...

sorry, my aim is not limited to one particular program. Yes, many
library can
permit you to respond to keyboard event, however, what I want is a
universal
function. as long as a key is pressed, no matter where, my program can
repond.
I am quite strange with this topic. But according to my understanding,
any event, keyboard event
for example, once triggered, will be dilivered by keyboard driver to X
system, and then
any running program can either choose to respond or ignore. So my
question can be translated to:
how to make my program respond ?

Do you want to intercept the call (prevent that it is passed through to
e.g. emacs), or are you merely interested in getting it? If the latter,
you can (as root) access the /dev/input keyboard device and get the
scan-codes.
The former is more complicated - without research I don't know out of my
head how to accomplish that. But it must be possible, as e.g. KDE
observes global key-shortcuts. Most probably a X-server thing.

thanks, right now I am content with just knowing a key is pressed.
as you said, I checked /etc/input/event1 which seems the input of
keyboard. Then I got some extremely strange code. however, how can

If you are on Linux, use XLib http://python-xlib.sourceforge.net/
You need to catch the KeyPress or KeyRelease X events.
while 1:
ev = display.next_event()
if ev.type == X.KeyPress:
key_code = ev.detail

The routines listed above aren't in the kernel. They're in
libc just like routines such as printf, memcpy, etc. The above
libc routines do make system calls into the kernel to perform
the desired functions, but those routines are not in the
kernel, and calling them is certainly not "kernel coding".
Yes, Python provides specific wrappers for many C library

Yes, the ctypes module provides a generic method for calling

tinypy rewritten in assembly probably could do the kernel job. CPython is
far too big for the kernel.
Another crazy idea. What about initd/launchd replacement in pure Python?
Python would be the first PID. Isn't it more practical?

Not at all. Microsoft Research has issued a preview release of an
operating system called "Singularity" where the entire kernel and all
drivers are written as managed code. Since Python can now be used to write
managed code (via IronPython), Q.E.D.
