Solve the following python programming problem given the following code:
def get_meaning(self) : 
    "
        This determines the event coding of the subtree rooted in this verb phrase.
        
        Four methods are key in this process: get_upper(), get_lower(), get_code() 
        and match_transform().
        
        First, get_meaning() gets the verb code from get_code()
        
        Then, it checks passivity. If the verb is passive, then it looks within 
        verb phrases headed by [by, from, in] for the source, and for an explicit target
        in verb phrases headed by [at,against,into,towards]. If no target is found,
        this space is filled with 'passive', a flag used later to assign a target
        if it is in the grammatical subject position. 
        
        If the verb is not passive, then the process goes:
        
        1) call get_upper() and get_lower() to check for a grammatical subject 
        and find the coding of the subtree and children, respectively.
        
        2) If get_lower returned a list of events, combine those events with
        the upper and code, add to event list.
        
        3) Otherwise, combine upper, lower, and code  and add to event list
        
        4) Check to see if there are S-level children, if so, combine with
        upper and code, add to list. 
        
        5) call match_transform() on all events in the list
        
        
        Parameters
        ----------
        self: VerbPhrase object that called the method
       
        Returns
        -------
        events: list
                List of events coded by the subtree rooted in this phrase.

            Helper method to combine events, accounting for 
            missing sources, and  targets, passives, multiple-
            target passives, and codeless verbs.

    Fix the buggy line: self.sentence.metadata [id (local)] = [low, item, 5]

#Here is Python program to find the coding of the subtree and children, respectively.

self.sentence.metadata [id (local)] = [ev, item, 5]
