Solve the following python programming problem given the following code:
def get_rules(self, min_leverage = None, min_strength = None, min_support = None, min_p_value = None, item_list = None, filter_function = None) : 
    'Returns the rules array, previously selected by the leverage,
           strength, support or a user-defined filter function (if set)

           @param float min_leverage   Minum leverage value
           @param float min_strength   Minum strength value
           @param float min_support   Minum support value
           @param float min_p_value   Minum p_value value
           @param List item_list   List of Item objects. Any of them should be
                                   in the rules
           @param function filter_function   Function used as filter

return (rule.p_value >= min_p_value)

else : 
            if isinstance (item_list [0], basestring) : 
                items = [item.index for item in self.get_items (names = item_list)] 
for item_index in rule.lhs : 
           ...

    
    

    Fix the buggy line: if all ([leverage (rule), strength (rule), support (rule), p_value (item_list), item_list_set (rule), filter_function_set (rule)]) :
