Python使用min、max函数查找二维数据矩阵中最小、最大值的方法
本文实例讲述了Python使用min、max函数查找二维数据矩阵中最小、最大值的方法。分享给大家供大家参考，具体如下：
简单使用min、max函数来得到二维数据矩阵中的最大最小值，很简单，这是因为工作需要用到一个东西所以先简单来写了一下：
#!usr/bin/envpython #encoding:utf-8 ''''' __Author__:沂水寒城 功能：找出来随机生成矩阵中的最大、最小值 ''' importtime importrandom defrandom_matrix_genetor(n=10): ''''' 功能:生成随机矩阵 输入：矩阵维数 输出：矩阵 ''' data_matrix=[] foriinrange(n): one_list=[] forjinrange(n): one_list.append(random.randint(1,100)) data_matrix.append(one_list) returndata_matrix deffind_martrix_min_value(data_matrix): ''''' 功能：找到矩阵最小值 ''' new_data=[] foriinrange(len(data_matrix)): new_data.append(min(data_matrix[i])) print'data_matrix最小值为：',min(new_data) deffind_martrix_max_value(data_matrix): ''''' 功能：找到矩阵最大值 ''' new_data=[] foriinrange(len(data_matrix)): new_data.append(max(data_matrix[i])) print'data_matrix最小值为：',max(new_data) if__name__=='__main__': data_matrix=random_matrix_genetor(20) printdata_matrix find_martrix_min_value(data_matrix) find_martrix_max_value(data_matrix)
结果如下：
