out_massive = []
current_matrix = get_the_first_matrix() # или ноль?? или матрица с нулями?
for i in range(0, 80):
current_matrix = get_the_first_matrix(current_matrix)
current_matrix = get_the_second_matrix(current_matrix)
current_matrix = get_the_third_matrix(current_matrix)
out_massive.append(current_matrix)
так?
