Write a Python function that takes a 2D matrix as input and returns True if it is a square matrix (i.e., the number of rows is equal to the number of columns), and False otherwise. def is square_matrix(matrix): rows = for if return matrix1 = [ ] matrix2 = [ in return [1, 2, 3, 4], [5, 6, 7], [9, 10, 11, 12] [1, 2, 3], [5, 6, 7], [9, 10, 11] != ] print (is_square_matrix(matrix1)) # False print(is_square_matrix (matrix2)) # True Activa Go to Se
