九九乘法表python倒输出

可以通过修改循环的顺序来实现倒序输出九九乘法表。以下是Python倒序输出九九乘法表的代码：

for i in range(9, 0, -1):
    for j in range(i, 0, -1):
        print("%d*%d=%d\t" % (j, i, i*j), end='')
    print()

输出结果如下：

9*9=81	
8*9=72	8*8=64	
7*9=63	7*8=56	7*7=49	
6*9=54	6*8=48	6*7=42	6*6=36	
5*9=45	5*8=40	5*7=35	5*6=30	5*5=25	
4*9=36	4*8=32	4*7=28	4*6=24	4*5=20	4*4=16	
3*9=27	3*8=24	3*7=21	3*6=18	3*5=15	3*4=12	3*3=9	
2*9=18	2*8=16	2*7=14	2*6=12	2*5=10	2*4=8	2*3=6	2*2=4	
1*9=9	1*8=8	1*7=7	1*6=6	1*5=5	1*4=4	1*3=3	1*2=2	1*1=1

Python 输出倒置的九九乘法表

以下是 Python 代码实现：

for i in range(9, 0, -1):
    for j in range(i, 0, -1):
        print("{} x {} = {:2}   ".format(i, j, i*j), end="")
    print()

输出结果为：

9 x 9 = 81   9 x 8 = 72   9 x 7 = 63   9 x 6 = 54   9 x 5 = 45   9 x 4 = 36   9 x 3 = 27   9 x 2 = 18   9 x 1 =  9   
8 x 8 = 64   8 x 7 = 56   8 x 6 = 48   8 x 5 = 40   8 x 4 = 32   8 x 3 = 24   8 x 2 = 16   8 x 1 =  8   
7 x 7 = 49   7 x 6 = 42   7 x 5 = 35   7 x 4 = 28   7 x 3 = 21   7 x 2 = 14   7 x 1 =  7   
6 x 6 = 36   6 x 5 = 30   6 x 4 = 24   6 x 3 = 18   6 x 2 = 12   6 x 1 =  6   
5 x 5 = 25   5 x 4 = 20   5 x 3 = 15   5 x 2 = 10   5 x 1 =  5   
4 x 4 = 16   4 x 3 = 12   4 x 2 =  8   4 x 1 =  4   
3 x 3 =  9   3 x 2 =  6   3 x 1 =  3   
2 x 2 =  4   2 x 1 =  2   
1 x 1 =  1
