[Python (py3)] Using import numpy as np, import sys, and def functions Please create a code that solves for matrix addition, matrix scalar multiplication, and matrix multiplication The input will come from file1.txt, and the output should be printed to output.txt Note for matrix addition: When the dimension of Matrix A is not equal to the dimension of Matrix B, print "Matrix addition cannot be performed; dimensions are unequal." Note for matrix multiplication: When the number of columns of Matrix A is not equal to the number of rows of Matrix B, print "Matrix multiplication cannot be performed; number of columns of Matrix A is not equal to number of rows of Matrix B." Format of the input from file1.txt: First Line: type of operation (add or scalmultiply or multiply) Second Line: matrix A dimension (example: if 3 rows and 2 columns, type 3 2) Third Line: matrix A elements Fourth Line: matrix B dimension (or the scalar number for the operation of scalar multiplication) Fifth Line: matrix B elements (not needed for scalar multiplication) Sample input 1: add 2 2 53 -4 7 31 2 2 67 2 -34 6 Sample output 1: 120 -2 -27 37 Sample input 1.1: add 2 2 53 -4 7 31 2 3 67 2 1 -34 6 2 Sample Output 1.1: Matrix addition cannot be performed; dimensions are unequal.

Using import numpy as np, import sys, and def functions
Please create a code that solves for matrix addition, matrix scalar multiplication, and matrix multiplication
The input will come from file1.txt, and the output should be printed to output.txt
Note for matrix addition: When the dimension of Matrix A is not equal to the dimension of Matrix B, print "Matrix addition cannot be performed; dimensions are unequal."
Note for matrix multiplication: When the number of columns of Matrix A is not equal to the number of rows of Matrix B, print "Matrix multiplication cannot be performed; number of columns of Matrix A is not equal to number of rows of Matrix B."
Format of the input from file1.txt:
First Line: type of operation (add or scalmultiply or multiply)
Second Line: matrix A dimension (example: if 3 rows and 2 columns, type 3 2)
Third Line: matrix A elements
Fourth Line: matrix B dimension (or the scalar number for the operation of scalar multiplication)
Fifth Line: matrix B elements (not needed for scalar multiplication)
