当python finally遇到break和sys.exit

except lite.Error, e:    print "Error %s:" % e.args[0]    sys.exit(1)    print '++++++++++++++++++++++'finally:    print "---------------"

finally会不会执行?

在google搜：sys.exit finally第一个：

All sys.exit() does is raise an exception of type SystemExit.！

python很聪明的！

另外一种情况在循环中break

import Queueimport threadingimport timeimport sysworkQueue = Queue.Queue(10)for i in range(0,6):    workQueue.put(i)    def thread_get():    print 'i am starting------'    while  True:        try:            req = workQueue.get()            break            print 'aaaaaaaaa'        except Exception,qe:            print 'enmpty-----------'            break        finally:            print 'i finally'            workQueue.task_done()            for i in range(0,5):    t = threading.Thread(target=thread_get)    t.setDaemon(True)    t.start()workQueue.join()print "Exiting Main Thread"

        

       Py官网说的：When a return, break or continue statement is executed in the try suite of a try...finally statement, the finally clause is also executed ‘on the way out.’ A continue statement is illegal in the finally clause. (The reason is a problem with the current implementation — this restriction may be lifted in the future).

经过测试break后退出，造成task_done 死等

第一次测试竟然通过，，细查只正好放了5个数据进Queue！改成6个死锁！
