max in a list of tuples (Python)

Question

I have this list of list of tuples

var1 = [
    [(10, '?'), (7, '?')],
    [(14, '?'), (2, '?')],
    [(2, '?'), (9, '?')],
    [(11, '?'), (10, '?')],
    [(11, '?'), (5, '?')]
]

and I wanna extract the tuple with the maximun value which is the second one or var1[1]. I've used a lot of different codes during my programming but the one I'm using now and until now and didn't have any major issues is this one:

 maximo = max(var1, key=lambda x: sum(i for i,_ in x))

also this one:

 maximo2 = list(map(max,zip(*var1)))

问题是我需要具有最大值的列表，而不是具有 2 个最大值组合的列表，现在此代码输出var1[3]为 2 中较大的一个，我不知道还能尝试什么。

Answer 1

使用max代替sum

前任：

var1=[[(10, '?'), (7, '?')], [(14, '?'), (2, '?')], [(2, '?'), (9, '?')], [(11, '?'), (10, '?')], [(11, '?'), (5, '?')]]
maximo=max(var1, key=lambda x: max(i for i,_ in x))
print(maximo)

输出：

[(14, '?'), (2, '?')]
