在每行的末尾加0，等于两头加0. def f_yang(n): yang = [1] for i in range(n-1): yang.append(0) yang = [yang[j-1] + yang[j] for j in range(len(yang))] print(yang) ...

直接看代码: list2 = [random.randint(1, 9) for _ in range(9)] print(list2) count_swap_2 = 0 count_iter_2 = 0 list3 = list2.copy() count_swap_3 = 0 count_iter_3 = 0 #升级版的冒泡法:鸡尾酒排序法(交换次数一样,迭代次数减少了.) for i i...
