If you are on Windows and want to trap the Ctrl-C combination, just catch  
the KeyboardInterrupt exception:

--- cut ---
 from time import sleep

while 1:
   try: sleep(1)
   except KeyboardInterrupt: print "Ctrl-C pressed"
--- cut ---

Your humble opinion is wrong.

Under windows Ctrl-C raises KeyboardInterrupt just as it does under 
linux. Ctrl-break by default terminates the program (without invoking 
Python's usual cleanup), but you can override that behaviour by 
registering a different signal handler.

e.g.

  import signal
  signal.signal(signal.SIGBREAK,
signal.default_int_handler)

will make Ctrl-break raise KeyboardInterrupt just like Ctrl-C.

No it is KeyboardInterrupt in Windows too.

depends on where you got your input from and what do you exactly want

eg:
in a gui app you get input events from the gui toolkit (wx, gtk, sdl/
pygame...)
in a console app if you use curses lib then you can use getch() oslt

if you want a general solution to get input key events in a simple 
script then you cannot do that.

however Ctrl+C is a special key combination: running python in a unix 
terminal it raises KeyboardInterrupt exception, imho in a windows cmd 
promt it raises SystemExit

so you can emulate those by using:
raise KeyboardInterrupt
or
raise SystemExit

hope this helps

Hi;
How can I know the Key c and Ctrl on the keyboard are pressed? Or how 
to let the program press the

key Ctrl+c automatically? I just want to use python to develop a 
script program.
