python 打印99乘法口诀

for i in range(1,10):
    for h in range(1,i+1):
        print('%sx%s='%(h,i),i*h,end='  ')  #这段也可以实现：print('{}x{}={}\t'.format(j, i, i*j), end='')
    print()

执行结果：

1x1= 1  
1x2= 2  2x2= 4  
1x3= 3  2x3= 6  3x3= 9  
1x4= 4  2x4= 8  3x4= 12  4x4= 16  
1x5= 5  2x5= 10  3x5= 15  4x5= 20  5x5= 25  
1x6= 6  2x6= 12  3x6= 18  4x6= 24  5x6= 30  6x6= 36  
1x7= 7  2x7= 14  3x7= 21  4x7= 28  5x7= 35  6x7= 42  7x7= 49  
1x8= 8  2x8= 16  3x8= 24  4x8= 32  5x8= 40  6x8= 48  7x8= 56  8x8= 64
