# Python Equality List | A program for checking the identity of two given matrices

|

Examples:

` Input: A = [[1, 1, 1, 1], [2, 2, 2, 2], [3, 3, 3, 3], [4, 4, 4, 4]] B = [[1, 1, 1, 1], [2, 2, 2, 2], [3, 3, 3, 3], [4, 4, 4, 4]] Output: Matrices are identical `

We have a solution to this problem, please refer to a C program to check if two given matices are identical by reference. In python, any iterable object is comparable, so we can quickly solve this problem in python with List Equality .

` `

` # Function for checking identity of two given matrices   def identicalMatrices (A, B):   if A = = B: print ( ’Matrices are identical’ ) else :  print ( ’Matrices are not identical’ )    # Driver program if __ name__ = = "__ main__" :   A = [[ 1 , 1 , 1 , 1 ],   [ 2 , < / code> 2 , 2 , 2 ], [ 3 , 3 , 3 , 3 ], [ 4 , 4 , 4 , 4 ]]      B = [[[ 1 , 1 , 1 , 1 ], [ 2 , 2 , 2 , 2 ], [ 3 , 3 , 3 , 3 ], [ 4 , 4 , 4 , 4 ]] identicalMatrices (A, B) `

` `

Output:

` Matrices are identical `
