Solve the following python programming problem given the following code:
def __getitem__(self, index) : 
    def expand_record(record, parent = None) : 
        ret = { 
            
} 
        for (key, value) in record.items () : 
            if parent : 
                full_key = ((parent + '.') + key) 
else : 
                full_key = key 
if (type (value) == dict) : 
                expanded = expand_record (value, full_key) 
                ret.update (expanded) 
else : 
                ret [full_key] = value 
return ret 
record = self.resultset.__getitem__ (record) 
    if (not self.expand) : 
        return record 
else : 
        return expand_record (record) 

    
    

    Fix the buggy line: record = self.resultset.__getitem__ (record)

#Here is Python program to fix the buggy line: record = self.

record = self.resultset.__getitem__ (index)
