用itertools模块做，主要是练习使用模块

1. from itertools import product
   
2. s=product(range(1,10),repeat=2)
   
3. count=1
   
4. for i in s:
   
5.     if count<9:
   
6.         x=i[0]*i[1]
   
7.         print(x,end=" ")
   
8.         count+=1
   
9.     else:
   
10.         x=i[0]*i[1]
    
11.         count=1
    
12.         print(x)

看了前面其他楼的答案，再修改

1. from itertools import product
   
2. s=product(range(1,10),repeat=2)
   
3. count=1
   
4. for i in s:
   
5.     if count<9:
   
6.         x=i[0]*i[1]
   
7.         print("%s*%s=%2s"%(i[0],i[1],x),end=" ")
   
8.         count+=1
   
9.     else:
   
10.         x=i[0]*i[1]
    
11.         count=1
    
12.         print("%s*%s=%2s"%(i[0],i[1],x))

你这个打印不标准啊
99乘法表的标准输出是这样的：
1 x 1 =  1   

total += '%d x %d = %2d    ' % (j, i, i * j) if i != j else '%d x %d = %2d    \n' % (j, i, i * j)

这个是怎么实现转行的？？我换了下形式就不可以了？？
if i != j:
       total += '%d x %d = %2d ' % (j, i, i * j)
       else:
             '%d x %d = %2d \n' % (j, i, i * j)

优雅的我不会

没有转行符号 为什么会自动转行呢？？

这位鱼油写的我能看懂，本人实属想不开其他易懂的代码了，恩这个在字符串中添加回车的方法我学会了count是为了控制两个回车之间的间隔恩感谢您的答案
t = ''
for x in range(1,10):
    count = 1
    for y in range(1,x+1):
        if x == y:
            t += ('%d * %d = %d\n' % (x , y , x * y))
            count = 0
        if count != 0:
            t += ('%d * %d = %d' % (x , y , x * y))

print(t)
