I wrote the below code

    if isinstance(gate_seq, Number):
        if return_as_muls:
            return {(Integer(1), Integer(1))}
        else:
            return {((), ())}
    elif isinstance(gate_seq, Mul):
        gate_seq = gate_seq.args
    queue = deque()
    rules = set()
    max_ops = len(gate_seq)
    def process_new_rule(new_rule, ops):
        if (new_rule is not None):
            (new_left, new_right) = new_rule
            if ((new_rule not in rules) and ((new_right, new_left) not in rules)):
                rules.add(new_rule)
            if ((ops + 1) < max_ops):
                queue.append((new_rule + ((ops + 1),)))
    queue.append((gate_seq, (), 0))
    rules.add((gate_seq, ()))
    while (len(queue) > 0):
        (left, right, ops) = queue.popleft()
        new_rule = ll_op(left, right)
        process_new_rule(new_rule, ops)
        new_rule = lr_op(left, right)
        process_new_rule(new_rule, ops)
        new_rule = rl_op(left, right)
        process_new_rule(new_rule, ops)
        new_rule = rr_op(left, right)
        process_new_rule(new_rule, ops)
    if return_as_muls:
        mul_rules = set()
        for rule in rules:
            (left, right) = rule
            mul_rules.add((Mul(*left), Mul(*right)))
        rules = mul_rules
    return rules

What's a good function header?
