keyboardinterrupt

I'm writing python 2.6.6 code on windows that looks like this: try: dostuff() except KeyboardInterrupt: print "Interrupted!" except: print "Some other exception?" finally: print "cleaning up...." print "done." dostuff() is a function that loops forever, reading a line at a time from an input stream and acting on it. I want to be able to stop it and clean up when I hit ctrl-c. What's happening instead is that the code under except KeyboardInterrupt: isn't running at all. The only thing that gets printed is "cleaning up...", and then a traceback is printed that looks like this: Traceback (most

I'm writing a command line utility in Python which, since it is production code, ought to be able to shut down cleanly without dumping a bunch of stuff (error codes, stack traces, etc.) to the screen. This means I need to catch keyboard interrupts. I've tried using both a try catch block like: if __name__ == '__main__': try: main() except KeyboardInterrupt: print 'Interrupted' sys.exit(0) and catching the signal itself (as in this post ): import signal import sys def sigint_handler(signal, frame): print 'Interrupted' sys.exit(0) signal.signal(signal.SIGINT, sigint_handler) Both methods seem to

I'm running 64-bit Python 2.7.3 on Win7 64-bit. I can reliably crash the Python interpreter by doing this: >>> from scipy import stats >>> import time >>> time.sleep(3) and pressing Control-C during the sleep. A KeyboardInterrupt is not raised; the interpreter crashes. The following is printed: forrtl: error (200): program aborting due to control-C event Image PC Routine Line Source libifcoremd.dll 00000000045031F8 Unknown Unknown Unknown libifcoremd.dll 00000000044FC789 Unknown Unknown Unknown libifcoremd.dll 00000000044E8583 Unknown Unknown Unknown libifcoremd.dll 000000000445725D Unknown

I am running a script, but it is taking much too long so I want to terminate the script. However it has calculated a lot of data which I would ideally not want to throw away. Is there an alternative to ctrl-C with which you save the internal function variables to the workspace? Ideally I'm looking for a Matlab keyboard shortcut like ctrl-C , but if that really can't be done maybe there is a way to do this in the script of my function. Any idea how to let my script react to ctrl-C as well, or maybe a GUI element which I can cancel and then I save the variables through my script? Some similar

I'm running this simple code: import threading, time class reqthread(threading.Thread): def run(self): for i in range(0, 10): time.sleep(1) print('.') try: thread = reqthread() thread.start() except (KeyboardInterrupt, SystemExit): print('\n! Received keyboard interrupt, quitting threads.\n') But when I run it, it prints $ python prova.py . . ^C. . . . . . . . Exception KeyboardInterrupt in <module 'threading' from '/usr/lib/python2.6/threading.pyc'> ignored In fact python thread ignore my Ctrl + C keyboard interrupt and doesn't print Received Keyboard Interrupt . Why? What is wrong with this
