How to use the max function in a two-dimensional list

This time I will show you how to use the max function in a two-dimensional list. What are the precautions when using the max function in a two-dimensional list. The following is a practical case. Let’s take a look.

I discovered this recently while writing an algorithm related to two-dimensional lists

When max is used to find the maximum value in a two-dimensional list, the output result is the list with the largest first element of the sublist

The test is as follows

c=[[1,2,-1],[0,5,6]] 
a=[[0,3,-1],[1,4,6]] 
print(max(c),max(a))

The result is like this

[1, 2, -1] [1, 4, 6]

I believe it After reading the case in this article, you have mastered the method. For more exciting information, please pay attention to other related articles on the PHP Chinese website!
