主要是用到了 collections 里面的Counter函数
import numpy as np
from collections import Counter
rows=10
cols=9
arr=np.random.random_integers(1,10,(10,9))#生成整数数组
print("二维数组元素:",arr)
result = [Counter(arr[:, i]).most_common(1)[0] for i in range(cols)]
print("按列统计的结果为:",result)#显示的结果中第一个是数字,第二个是这个数字出现的次数
result = [Counter(arr[i, :]).most_common(1)[0] for i in range(rows)]
print("按行统计的结果为:",result)
--------------------------------------------------------------------------------
二维数组元素: [[ 9 5 10 8 6 9 4 7 9]
[ 4 9 5 3 9 9 3 2 5]
[ 6 3 3 8 7 1 9 1 5]
[ 8 10 6 8 3 10 7 10 7]
[ 8 6 1 9 4 10 3 4 4]
[ 2 5 9 8 7 6 5 6 3]
[ 4 1 4 4 8 9 4 10 6]
[ 9 5 8 8 10 2 1 2 2]
[ 2 1 9 5 3 7 8 3 4]
[ 6 9 7 10 3 2 10 8 2]]
按列统计的结果为: [(9, 2), (5, 3), (9, 2), (8, 5), (3, 3), (9, 3), (4, 2), (2, 2), (5, 2)]
按行统计的结果为: [(9, 3), (9, 3), (3, 2), (10, 3), (4, 3), (5, 2), (4, 4), (2, 3), (3, 2), (10, 2)]
