Solve the following python programming problem given the following code:
def _check_bit_flag_sets_properties_falsy_or_negative(self, query_sequences = None, target_sequences = None, arg_settings = [], properties_to_null = []) : 
    kwarg = { 
        
} 
    def falsy_or_negative(alignment, prop) : 
        if (type (alignment [prop]) is int) : 
            return (alignment [prop] < 0) 
else : 
            return (not alignment [prop]) 
for query_sequence in query_sequences : 
        for target_sequence in target_sequences : 
            for (arg, setting) in arg_settings : 
                kwarg [arg] = setting 
query = StripedSmithWaterman (query_sequence, ** kwarg) 
            alignment = query (kwarg) 
            for prop in properties_to_null : 
                self.assertTrue (falsy_or_negative (alignment, prop)) 
for prop in [p for p in self.align_attributes if (p not in properties_to_null)] : 
                self.assertFalse (falsy_or_negative (alignment, prop)) 

    
    

    Fix the buggy line: alignment = query (kwarg)

#Here is Python code to fix the buggy line: alignment = query (kwarg)
.

alignment = query (target_sequence)
