emmm为什么这里运行的结果只会出现一种，比如prize[0] and prize[1],只出现prize[1...

import random
prize = ["金币","钻石","一日体验卡","皮肤体验卡","限定皮肤","新品英雄"]
i = 3
summary = 0
while i:
    a = random.randint(0,2)
    summary = summary + a
    i -= 1
    continue
if summary == 6:
    print(prize and prize)
elif 3 <= summary < 6:
    print(prize and prize)
else:
    print(prize and prize)

事实上，用了or也不行

打印多个内容需要用逗号分隔，不能用 and，and 属于逻辑操作符：

import random

prize = ["金币", "钻石", "一日体验卡", "皮肤体验卡", "限定皮肤", "新品英雄"]
i = 3
summary = 0
while i:
    a = random.randint(0, 2)
    summary = summary + a
    i -= 1
    continue
if summary == 6:
    print(prize, prize)
elif 3 <= summary < 6:
    print(prize, prize)
else:
    print(prize, prize)

如果想让prize与prize随机出现，那是需要重设条件吗

不用，这样即可：

import random

prize = ["金币", "钻石", "一日体验卡", "皮肤体验卡", "限定皮肤", "新品英雄"]
i = 3
summary = 0
while i:
    a = random.randint(0, 2)
    summary = summary + a
    i -= 1
    continue
if summary == 6:
    print(prize)    # 从 prize 和 prize 之中随机选择一个
elif 3 <= summary < 6:
    print(prize)    # 从 prize 和 prize 之中随机选择一个
else:
    print(prize)    # 从 prize 和 prize 之中随机选择一个
