Matrix_addition.py

"""
In mathematics, matrix addition is the operation of adding two matrices by adding 
the corresponding entries together.This program takes two matrices of order r*c and 
stores it in two-dimensional array. Then, the program adds these two matrices and 
displays it on the screen.

Enter the number of rows for second matrix : 3
Enter the number of columns for second matrix : 3
Enter the entries rowwise:
