            i = int(input(s))

    return i

    while True:

            print(f'还剩{sum_num - len(lucks)}没有中奖，请重新输入中奖人数。')
            luck_num = num('请输入中奖人数：')

    while j < luck_num:
        temp = rd.choice(range(1,sum_num+1))
        if temp in lucks:
            print(temp,'重复了！')
            continue
        else:
            lucks.append(temp)
            round_luck.append(temp)
            print(f'第{j+1}个中奖者是',':',temp)
        j += 1
    print(f'第{i+1}次中奖者{len(round_luck)}位是：',round_luck)
    i += 1

unlucks = []
for k in range(1,sum_num+1):
    if k not in lucks:
        unlucks.append(k)

unlucks.sort()
lucks.sort()
print(f'得奖人数是{len(lucks)}，分别为：',lucks)
print(f'没有得奖人数是{len(unlucks)}，分别为：',unlucks)

个人觉得纯练习挺好，但如果要做到现实可用至少应该做到界面化并且能互动才行，比如设置好后鼠标点一下，开始抽奖，再点一下停止之类。

random生成伪随机数，考虑numpy.random.choice

有随机选取元素的现成方法，或者打乱顺序使用pop抽奖
