python两则99乘法表

分别应用while和for的嵌套循环，适用于初学的人看看

x = 1
while x <= 9:
    y = 1
    while y <= x:
        print (y,‘*‘,x,‘=‘,x*y,end="\t")
        y += 1
    print ("")
    x += 1

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

for i in range(1,10):
    for j in range(1,1+i):
        print ("%dx%d=%d\t"%(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
1x9=9	2x9=18	3x9=27	4x9=36	5x9=45	6x9=54	7x9=63	8x9=72	9x9=81
