小白Python练习册（14）【鱼币福利】

现在是11:30我都已经躺下了
但想起来今天没出题{:10_266:}
赶紧又起来了
（冰河星云最近有事，不出意外的话最近都是我出题）{:10_250:}
我太难了{:10_285:}

开始出题吧：

输出乘法口诀表
（你不会以为就这么简单吧？不可能！）

今天我们不仅要输出正常的乘法口诀表，我们还要输出反向的，上效果：

==========我会帮您输出乘法口诀表==========

您要正向还是反向(正/反)：反
9 * 9 = 81 9 * 8 = 72 9 * 7 = 63 9 * 6 = 54 9 * 5 = 45 9 * 4 = 36 9 * 3 = 27 9 * 2 = 18 9 * 1 = 9
8 * 8 = 64 8 * 7 = 56 8 * 6 = 48 8 * 5 = 40 8 * 4 = 32 8 * 3 = 24 8 * 2 = 16 8 * 1 = 8
7 * 7 = 49 7 * 6 = 42 7 * 5 = 35 7 * 4 = 28 7 * 3 = 21 7 * 2 = 14 7 * 1 = 7
6 * 6 = 36 6 * 5 = 30 6 * 4 = 24 6 * 3 = 18 6 * 2 = 12 6 * 1 = 6
5 * 5 = 25 5 * 4 = 20 5 * 3 = 15 5 * 2 = 10 5 * 1 = 5
4 * 4 = 16 4 * 3 = 12 4 * 2 = 8 4 * 1 = 4
3 * 3 = 9 3 * 2 = 6 3 * 1 = 3
2 * 2 = 4 2 * 1 = 2
1 * 1 = 1
==========我会帮您输出乘法口诀表==========您要正向还是反向(正/反)：fan
您的输入有误！
请重新输入
您要正向还是反向(正/反)：正
1 * 1 = 1
2 * 1 = 2 2 * 2 = 4
3 * 1 = 3 3 * 2 = 6 3 * 3 = 9
4 * 1 = 4 4 * 2 = 8 4 * 3 = 12 4 * 4 = 16
5 * 1 = 5 5 * 2 = 10 5 * 3 = 15 5 * 4 = 20 5 * 5 = 25
6 * 1 = 6 6 * 2 = 12 6 * 3 = 18 6 * 4 = 24 6 * 5 = 30 6 * 6 = 36
7 * 1 = 7 7 * 2 = 14 7 * 3 = 21 7 * 4 = 28 7 * 5 = 35 7 * 6 = 42 7 * 7 = 49
8 * 1 = 8 8 * 2 = 16 8 * 3 = 24 8 * 4 = 32 8 * 5 = 40 8 * 6 = 48 8 * 7 = 56 8 * 8 = 64
9 * 1 = 9 9 * 2 = 18 9 * 3 = 27 9 * 4 = 36 9 * 5 = 45 9 * 6 = 54 9 * 7 = 63 9 * 8 = 72 9 * 9 = 81
不能直接用print，要使用for循环啊！{:10_256:}

回复查看参考答案啊：

这也用到for循环了{:10_256:}from sys import stdout

用for循环输出多行文字的大哥真的猛{:10_256:}

看见以上大佬个个这么简洁，写不出了
