问些Python选择判断题

帮Python小小白看看题目吧qaq我真的对这些都一窍不通，其实也就知道个答案就好啦，谢谢！！

这最后怎么输出这个二元组呀，希望有人可以详细写一个给我看看，万分感谢！

[2]石头剪刀布

# 读入两个人的猜拳
first, second = input().split('>')

# 判断胜负并输出结果
if first == '石头' and second == '剪子':
    print('前者赢')
elif first == '剪子' and second == '布':
    print('前者赢')
elif first == '布' and second == '石头':
    print('前者赢')
elif first == second:
    print('平局')
else:
    print('后者赢')

【3】鸡兔同笼

data = input("请输入头和脚的数目，数据之间用英文逗号隔开：")
heads, legs = map(int, data.split(","))
x = (legs - 2 * heads) // 2
y = heads - x
if legs % 2 == 0 and x >= 0 and y >= 0:
    print((x, y))
else:
    print("无解")
