If you give me a number and a string, I'm going to concatenate them together, it's really different operations, but nonetheless, it's what it's going to do.
如果给的输入是一个数字和一个字符串,我将会把它们连接在一起,这实在是不正确的操作,但是无论如何,它就是会去这么做。
As we saw before, it simply concatenates them together and gives me back a longer string.
和我们之前学过的一样,这个操作会把两个字符串连接起来。
We'd like to do the same thing with strings.
我们也可以把字符串连接到一起。
I don't happen to like this, but he thinks that is, give a combination of a number multiplication in a string, this will in fact give us back a new string with that many replicas, if you like, of the string concatenated together.
我不喜欢这么做但是他认为,也就是说,返回一个字符串的,某个特定数字的倍数,这实际上会返回一个新字符串,一个原来的字符串的很多复制品,连接到一块的一个字符串。
And again, if I just run this, just to show that it's going to do the right thing, it says enter base, I'm obnoxious, it says oops, wasn't a float, so we'll be nice about it and I enter a height, and it prints out what I expected. I just concatenated those strings together, by the way, at the end.
我再来运行下看是不是做对了,提示输入底,噢,它提示说不是浮点数,我很高兴,然后我输入一个,浮点数作为高度显示结果和我预期的相同,顺便说一句,我只是在最后把这些字符串连接起来了。
