如何返回元组而不是联合

def get_tuple():
    a = 1
    b = 2
    return a, b

result = get_tuple()
print(result)  # 输出 (1, 2)

def get_tuple():
    a = 1
    return (a,)

result = get_tuple()
print(result)  # 输出 (1,)

struct Tuple {
    int a;
    int b;
};

Tuple get_tuple() {
    Tuple tuple;
    tuple.a = 1;
    tuple.b = 2;
    return tuple;
}

Tuple result = get_tuple();
printf("(%d, %d)\n", result.a, result.b);  // 输出 (1, 2)
