So notice the nesting, I can flow my way through how those tests are actually going to take place.
请注意嵌套,我可以跳过,其中不执行一些语句。
You can say if this is true, then go and do the following pieces of code or puzzle pieces that are inside this part of the block, else go ahead and do these that are down here.
你可以说如果条件成立,执行下面的代码段,或板块中的拼图,否则跳过去执行这下面的语句。
So what we've seen is I've run it twice here.
我们现在看到的就是,我执行了这条打印语句两次。
All right? So if I called sqrt alone, that return test value is done, but in this case I bound it to test, so I can go look at test, and there it is.
执行完返回值语句,但是在这里我将把它赋值给,所以当我看test的值的时候就是返回的值。
