Load Random Images from Directory I'd like to randomly load images from a directory and have a button somewhere that refreshes the entire page. Here's the current code I have now: <?php $a = array(); $dir = '../public/wp-content/uploads/2012/01'; if ($handle = opendir($dir)) { while (false !== ($file = readdir($handle))) { if (preg_match("/.png$/", $file)) $a = $file; elseif (preg_match("/.jpg$/", $file)) $a = $file; elseif (preg_match("/.jpeg$/", $file)) $a = $file; } closedir($handle); } foreach ($a as $i) { echo "<img src='" . $dir .

Python how to include a string with random integer [duplicate] This question already has an answer here: I want to make a random police unit generator and the code is like so: import random unitnumbers = ('unit' , random.randint(1,999)) print(unitnumbers) However, rather than printing "unit 63" , it prints ('unit', 378) How could I make it print only the unit and random number? This question has been asked before and already has an answer.

You should instead make it a string like that: unitnumbers unitnumbers = "unit " + str(random.randint(1,999)) This should do that: import random unitnumbers = 'unit %d' % random.randint(1,999) print(unitnumbers)

how to generate random numbers from 1 to 4 and 8 in swift I'm making an iOS SpriteKit game right now for first time I'm developing any app and it's tough challenge for me because it's really a big project for first time. My game is a Dice game and I defined move as 4 number. So when ever I touch the screen Player moves 4 blocks, But now I want to add Dice to the Game and I need Numbers from 1 to 4 and 8. So it will be 1,2,3,4 and 8 Numbers in the Dice. I know in Swift we can get Random Numbers with "arc4random" but how do I get numbers 1 to 4 and also 8 can I do it with arc4random and if possible I need 4 and 8 numbers to come 20% more often.
