TODAY’S FOCUS–“for loop”
今日学习：for loop 循环 条件

First, if we want to print the following result, what can we do with for loop?
首先，看下下面的输出结果，我们应该怎么用循环语句？

1X1=1
1X2=2
1X3=3
1X4=4
1X5=5
1X6=6
1X7=7
1X8=8
1X9=9

The code is below, but there is a error inside, could you find it?
代码如下，但是里面有错误，你发现了吗？


You may notice that the ‘1X9=9’ did not show on the screen.
你也许注意到了，输出结果里少了1X9=9.

So, how to change the code?
那么应该如何更正代码呢？

Let’s have look at another example. The result is according to the user’s input number.
我们再看一个例子，这次是根据用户自己输入的数字，来确定计算到9乘以几。


So, you have learnt python ‘for loop’ in today’s lesson. See you next time.
