用itertools模块做，主要是练习使用模块
from itertools import product
s=product(range(1,10),repeat=2)
count=1
for i in s:
if count<9:
   x=i*i
   print(x,end=" ")
   count+=1
else:
   x=i*i
   count=1
   print(x)

看了前面其他楼的答案，再修改
from itertools import product
s=product(range(1,10),repeat=2)
count=1
for i in s:
if count<9:
   x=i*i
   print("%s*%s=%2s"%(i,i,x),end=" ")
   count+=1
else:
   x=i*i
   count=1
   print("%s*%s=%2s"%(i,i,x))

for i in range(1,10):
for j in range(1,10):
   if i >=j:
         print("%d*%d =%2d"%(i,j,i*j),end = " ")
         if i <= j :
            print()

print('{0}*{1}={2}'.format(j,i,i*j).ljust(8),end='')

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)
