在二维数组中查找最大值 [英] Finding the Max value in a two dimensional Array

问题描述

我正在尝试找到一种优雅的方法来在二维数组中找到最大值. 例如此数组:

I'm trying to find an elegant way to find the max value in a two-dimensional array. for example for this array:

[0, 0, 1, 0, 0, 1] [0, 1, 0, 2, 0, 0][0, 0, 2, 0, 0, 1][0, 1, 0, 3, 0, 0][0, 0, 0, 0, 4, 0]

我想提取值"4". 我想在max范围内做一个max，但是我在执行它时很挣扎.

I would like to extract the value '4'. I thought of doing a max within max but I'm struggling in executing it.

推荐答案

最大数量的最大值(map(max, numbers)产生1，2，2，3，4):

Max of max numbers (map(max, numbers) yields 1, 2, 2, 3, 4):

>>> numbers = [0, 0, 1, 0, 0, 1], [0, 1, 0, 2, 0, 0], [0, 0, 2, 0, 0, 1], [0, 1, 0, 3, 0, 0], [0, 0, 0, 0, 4, 0]

>>> map(max, numbers)
<map object at 0x0000018E8FA237F0>
>>> list(map(max, numbers))  # max numbers from each sublist
[1, 2, 2, 3, 4]

>>> max(map(max, numbers))  # max of those max-numbers
4
