Python程序查找矩阵中每一行的最大元素
给定一个矩阵,任务是找到每一行的最大元素。
例子:
Input : [1, 2, 3]
[1, 4, 9]
[76, 34, 21]
Output :
3
9
76
Input : [1, 2, 3, 21]
[12, 1, 65, 9]
[1, 56, 34, 2]
Output :
21
65
56
方法:方法很简单。这个想法是为 no_of_rows 运行循环。检查行内的每个元素并找到最大元素。最后,打印元素。下面是实现:
Python
# Python program to find maximum
# element of each row in a matrix
# importing numpy
import numpy
# Function to get max element
def maxelement(arr):
# get number of rows and columns
no_of_rows = len(arr)
no_of_column = len(arr[0])
for i in range(no_of_rows):
# Initialize max1 to 0 at beginning
# of finding max element of each row
max1 = 0
for j in range(no_of_column):
if arr[i][j] > max1 :
max1 = arr[i][j]
# print maximum element of each row
print(max1)
# Driver Code
arr = [[3, 4, 1, 8],
[1, 4, 9, 11],
[76, 34, 21, 1],
[2, 1, 4, 5]]
# Calling the function
maxelement(arr)
输出 :
8
11
76
5
