Method #1: Using For Loop (Static Input)<\/h3>\n
\n
# Give the matrix as static input and store it in a variable.\r\nmtrx = [[1, 5, 6], [11, 5, 4], [9, 34, 5]]\r\n# Calculate the number of rows of the given matrix by\r\n# calculating the length of the nested list using the len() function\r\n# and store it in a variable mtrxrows.\r\nmtrxrows = len(mtrx)\r\n# Calculate the number of columns of the given matrix by\r\n# calculating the length of the first list in the nested list\r\n# using the len() function and store it in a variable mtrxcols.\r\nmtrxcols = len(mtrx[0])\r\n# take a variable which stores the number of 1's in the row and initialize it with 0\r\nmaxOnes = 0\r\n\r\n# Loop till the given number of rows using the For loop.\r\nfor p in range(mtrxrows):\r\n # calculate the maximum element of the row using the max()\r\n # function and store it in a variable\r\n maxRowEle = max(mtrx[p])\r\n # print the maximum element of the given row\r\n print('The maximum element of the row {', p+1, '} is :', maxRowEle)\r\n<\/pre>\n
The maximum element of the row { 1 } is : 6\r\nThe maximum element of the row { 2 } is : 11\r\nThe maximum element of the row { 3 } is : 34<\/pre>\n
Method #2: Using For loop (User Input)<\/h3>\n
\n
# Give the number of rows of the matrix as user input using the int(input()) function\r\n# and store it in a variable.\r\nmtrxrows = int(input('Enter some random number of rows of the matrix = '))\r\n# Give the number of columns of the matrix as user input using the int(input()) function\r\n# and store it in another variable.\r\nmtrxcols = int(input('Enter some random number of columns of the matrix = '))\r\n# Take a list and initialize it with an empty value using [] or list() to say gvnmatrix.\r\nmtrx = []\r\n# Loop till the given number of rows using the For loop\r\nfor n in range(mtrxrows):\r\n # Inside the For loop, Give all the row elements of the given Matrix as a list using\r\n # the list(),map(),int(),split() functions and store it in a variable.\r\n l = list(map(int, input(\r\n 'Enter {'+str(mtrxcols)+'} elements of row {'+str(n+1)+'} separated by spaces = ').split()))\r\n # Add the above row elements list to gvnmatrix using the append() function.\r\n\r\n mtrx.append(l)\r\n \r\n\r\n# take a variable which stores the number of 1's in the row and initialize it with 0\r\nmaxOnes = 0\r\n\r\n# Loop till the given number of rows using the For loop.\r\nfor p in range(mtrxrows):\r\n # calculate the maximum element of the row using the max()\r\n # function and store it in a variable\r\n maxRowEle = max(mtrx[p])\r\n # print the maximum element of the given row\r\n print('The maximum element of the row {', p+1, '} is :', maxRowEle)\r\n<\/pre>\n
Enter some random number of rows of the matrix = 3\r\nEnter some random number of columns of the matrix = 3\r\nEnter {3} elements of row {1} separated by spaces = 1 6 2\r\nEnter {3} elements of row {2} separated by spaces = 10 14 1\r\nEnter {3} elements of row {3} separated by spaces = 6 9 11\r\nThe maximum element of the row { 1 } is : 6\r\nThe maximum element of the row { 2 } is : 14\r\nThe maximum element of the row { 3 } is : 11<\/pre>\n
