Python for else block

Found interesting thing in python a "for else" block wow The else block will get executed if the for is not terminated by a break             pobj = subprocess.Popen(cmd, bufsize=1024)             for i in range(4):                 retcode = pobj.poll()                 if retcode is not None:                     break                 time.sleep(30)             else:                 try:                     logger.warn('killing process %d' % pobj.pid)                     os.kill(pobj.pid, signal.SIGKILL)                 except:                     logger.exception('Error killing process')
