Pass argument into a function called within a function python

Question

I am trying to pass an event argument from a function to another. The example code that I have now is:

def handle_store(event):

 ds = event.dataset  
 save(ds,event) 


def save(ds,event): 

 
 ds.file_meta = event.file_meta
 ds.save_as(ds.SOPInstanceUID, write_like_original=False)

 return 0x0000   

handlers = [(evt.EVT_C_STORE, handle_store)]

The ds can be passed into the next save func but the event does not. Can someone help? Thanks
