小数据上两种做法差多少

只有 10 条数据时，两种判重的比较次数。运行下面这段程序：

def list_ops(n):
    ops = 0
    seen = []
    for i in range(n):
        for y in seen:
            ops += 1
        seen.append(i)
    return ops

def set_ops(n):
    ops = 0
    seen = set()
    for i in range(n):
        ops += 1
        seen.add(i)
    return ops

print(str(list_ops(10)) + "/" + str(set_ops(10)))
