如何在Windows上的Python中捕获SIGINT?
问题内容:
(类似于这个问题)
在UNIX上的Python 2.7下,在Python提示符下:
>>> import signal
>>> def handler(signal, frame):
... print 'welcome to the handler'
...
>>> signal.signal(signal.SIGINT, handler)
<built-in function default_int_handler>
我按ctrl-c
>>> welcome to the handler
>>>
在Windows上:
>>> import signal
>>> def handler(signal, frame):
... print 'welcome to the handler'
...
>>> signal.signal(signal.SIGINT, handler)
<built-in function default_int_handler>
在按ctrl-c时:
>>>
KeyboardInterrupt
>>>
我可以验证是否handler
已在python端将其安装为SIGINT的处理程序(调用signal.signal
第二个计时器将返回my
handler
)。如何在Windows上捕获SIGINT?
