ipython的atexit替代方案

Question

python有atexit模塊註冊函數在關閉解釋器之前運行。 This question很好，爲什麼不叫atexit。

我想知道是否有替代ipython註冊一個函數之前退出的東西已經運行與%run <name>？理想情況下，我想根據解釋器創建一個裝飾器，它可以在 模塊中工作寄存器。

感謝托馬斯K爲好評。如果他寫了一個答案，我會接受他的。

# exit_register runs at the end of ipython %run or the end of the python interpreter 
try: 
    def exit_register(fun, *args, **kwargs): 
     """ Decorator that registers at post_execute. After its execution it 
     unregisters itself for subsequent runs. """ 
     def callback(): 
      fun() 
      ip.events.unregister('post_execute', callback) 
     ip.events.register('post_execute', callback) 


    ip = get_ipython() 
except NameError: 
    from atexit import register as exit_register 


@exit_register 
def callback(): 
    print('I\'m done!') 


print('Running')
