It gets really kind of trippy if you wanna output a backslash, \ you can't just use the backslash, \\ you need to use backslash backslash because otherwise a single backslash is confused with the so called escape character.
如果你想输出一个反斜杠,估计又得迷糊了,实际上,你不能直接用,而是要,否则一个\可能会被误认为,是转义字符。
So you have what are called escape characters like backslash N that is the shorthand notation of telling the computer put a new line character here.
幸亏我们有一些类似反斜杠n的转义字符,这只是一种简化方式,用来告知电脑要在这新添一行。
