    def print(self):
        print(self.List)
    def __add__(self, m):
        result = Matrix([])
        for i in range(len(self.List)):
            for j in range(len(self.List[0])):
                result.List.append(self.List[i][j] + m.List[i][j])
        return result
        
m1 = Matrix([[1,2],[3,4]])
m2 = Matrix([[4,5],[6,7]])
