Last failure for the moment

matrix1 = [[1, -2], [-3, 4],]
matrix2 = [[2, -1], [0, -1]]
matrix3 = [[2, -1], [0, -1]]

matrix = []
def add_many(*matrix):
    for num in range(add_many().func_code.co_argcount):
        for i in range(len(matrix[num])):
            for j in range(len(matrix[num])):
                print(matrix[i][j] + matrix[i][j])

add_many(matrix1,matrix2)
