sys.exit
will cause the current process exit. sys.exit
将导致当前进程退出。 you can try POpen then use one one of 您可以尝试POpen,然后使用以下一项
Popen.send_signal()
Popen.kill()
Popen.terminate()
to cause the subprocess quit. 导致子进程退出。 for example:
例如:
subp = subprocess.Popen("some command" )
subp.send_signal( 9 );
def clicked():
process = subprocess.Popen(['sudo','openvpn','--config',var.get()])
def clicked2():
process.kill()
process is in another defined function so I cannot recall it, anyway i can recall that in another function? 进程在另一个定义的函数中,因此我无法调用它,无论如何我可以在另一个函数中调用它?
