why those implementation diffrent for doPrint and doPrintln in fmt package about the spacing in between arguments.

<p>In specific my curious mind wants to know why doPrint() do not insert a space in between two args. why it is designed like this, and on the other hand doPrintln() insert spaces between two arguments.</p> <p>without looking to those implementation it was obvious to me that both will produce same output, only doPrintln will insert an extra new line at the end. But seems like those two implementation about spacing in between arguments are also different, why it is like this?</p> <p>Link : <a href="https://github.com/golang/go/blob/master/src/fmt/print.go#L1105">print.go</a></p> <hr/>**评论：**<br/><br/>f2f: <pre><p>as rob pike said in 2010:</p> <blockquote> <p>[...] Println gives you a line of text with the elements nicely spaced, while Print adds no newline and adds spaces only when non-strings would abut, as in Print(2, 3). In short, Println is for when you&#39;re lazy, Print is for when you want more control but don&#39;t want to provide special formatting.</p> </blockquote></pre>barsonme: <pre><p>Ponder: <a href="https://play.golang.org/p/8M53XKti_T" rel="nofollow">https://play.golang.org/p/8M53XKti_T</a></p></pre>
