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[0]*i[1]
        print(x,end=" ")
        count+=1
    else:
        x=i[0]*i[1]
        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[0]*i[1]
        print("%s*%s=%2s"%(i[0],i[1],x),end=" ")
        count+=1
    else:
        x=i[0]*i[1]
        count=1
        print("%s*%s=%2s"%(i[0],i[1],x))

elbert

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()

concrete

for i in range(1,10):
    for j in range(1,i+1):
        print('{0}*{1}={2}'.format(j,i,i*j).ljust(8),end='')
    print()

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)
