Re: if else in the other way

Or you can use this which is essentially similar to jwkrahn's but a little bit more readable in this context

$a == 6 ? print "yes\n" : print "no\n";

but a little bit more readable Debatable :-) For a simple yes/no `print` like this you are probably right. For lengthier outputs with, perhaps, a conditional part in the middle your way involves a lot of repeated text which can obscure meaning. Personally, in such cases I find this layout `print qq{Fixed part }, ( conditional expression ) ? qq{True part } : qq{False part }, qq{Further fixed text here\n};` [download] more readable than this `( conditional expression ) ? print qq{Fixed part True part Further fixed text here\n} : print qq{Fixed part False part Further fixed text here\n};` [download] particularly if the condition doesn't require parentheses, but others will probably disagree. I would be more likely to write the latter using an `if ( ... ) { ... } else { ... }` construct anyway as the meaning is more widely familiar. Cheers, JohnGG	[reply] [d/l] [select]

I agree ;), and I agree that this is debatable, I am a fan of not repeating commands while using a ternary operator too, in fact, avoiding ternary operators all together should my code be maintained by someone else, however, my answer was relative to this simple requirement put forth by the OP, breaking jwkrahn's reply down for him/her.

Compared to jwkrahn's simple and clear version (with one `print`), this "improvement" (with `print` occurring twice) is a violation of the DRY principle. See also Perl Best Practices: Chapter 6 (Control Structures), Tabular Ternaries; and Chapter 2 (Code Layout), Ternaries.	[reply] [d/l] [select]
