How to get the maximum value of a single row and each column of a two-dimensional matrix in Python

This time I will bring you PythonHow to get the maximum value of each column of a single row of a two-dimensional matrix, how to get the maximum value of each column of a two-dimensional matrix in PythonWhat are the precautions, below This is a practical case, let’s take a look at it.

Because there is a small link in the project that requires this function, so I wrote a simple little function. The following is the specific implementation:

#!usr/bin/env python
#encoding:utf-8
'''

'''
def get_max_value(martix):
  '''
  得到矩阵中每一列最大的值
  '''
  res_list=[]
  for j in range(len(martix[0])):
    one_list=[]
    for i in range(len(martix)):
      one_list.append(int(martix[i][j]))
    res_list.append(str(max(one_list)))
  return res_list
if name == 'main':
  martix=[['1','2','3'],['3','5','0'],['5','6','2']]
  print get_max_value(martix)

The results are as follows:

['5', '6', '3']
