首先感谢甲鱼老师的视频,非常好看也易懂。
end""是啥意思呢,看到有些时候在用不是很懂。
另外想请教下
for i in range(1,8,2):
for j in range(1,10):
print('{}x{}={:3} '.format(i,j,i*j),end="")
print('{}x{}={:3} '.format(i+1,j+1,i*j),end="")
print('{}x{}={:3} '.format(i+2,j+2,i*j))
print()
这个第二次循环后怎么成了结果不对呢?

不吝赐教,拜上、
print的缺省状态是end="\n",即最后有一个回车,如果加上end ="",就代表输出内容后不换行。
我猜你想到得到这样的结果。
- 1x1= 1 2x1= 2 3x1= 3
- 1x2= 2 2x2= 4 3x2= 6
- 1x3= 3 2x3= 6 3x3= 9
- 1x4= 4 2x4= 8 3x4= 12

- 1x6= 6 2x6= 12 3x6= 18
- 1x7= 7 2x7= 14 3x7= 21
- 1x8= 8 2x8= 16 3x8= 24
- 1x9= 9 2x9= 18 3x9= 27
- 4x1= 4 5x1= 5 6x1= 6
- 4x2= 8 5x2= 10 6x2= 12

帮你改了程序
- for i in range(1,8,3):
- for j in range(1,10):
- print('{}x{}={:3} '.format(i,j,i*j),end="")
- print('{}x{}={:3} '.format(i+1,j,(i+1)*j),end="")
- print('{}x{}={:3} '.format(i+2,j,(i+2)*j))
- print()
