python，7- 小程序练习：循环语句for，while实现99乘法表

打印99乘法表

for 循环语句实现：

for i in range(1,10):
    for j in range(1,10):
        print(j,"x",i,"=",i*j,"\t",end="")   #因为print自动换行，end="" 为结尾不换行
        if i==j:
            print("")  #此处是结尾换行
            break

while循环语句实现：

i=0
j=0
while i <9:
    i+=1
    while j <9:
        j += 1
        print(j, "x", i, "=", i * j, "\t", end="")
        if i==j:
            print("")
            j=0
            break

输出结果：

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