   NumPy solution: numpy.random.choice. For this question, it works the same as the accepted answer (import random; random.choice()), but I added it because the programmer may have imported NumPy already (like me)

3. Python random sample with a generator / iterable / iterator

   15. If you are going to be getting a random element multiple times, you want to make sure your random number generator is initialized only once. private int[] items = new int[]{1,2,3}; private Random rand = new Random(); public int getRandArrayElement(){. return items[rand.nextInt(items.length)]; If you are picking random array elements that ...

   The item just needs to have a random x positon,which is generated within the constraints of the width of the container. The game is as bottom up scroller,with different platforms being generated. private Item[] generateRandomItems(int number){. Money[] items=new Money[number]; for(int i=0;i<number;i++){. Random r=new Random();

6. Getting a random value from a JavaScript array - Stack Overflow

   stackoverflow.com/questions/4550505

   First, to define the prototype function, place this snippet in your code: Array.prototype.sample = function(){. return this[Math.floor(Math.random()*this.length)]; } Later, to sample a random element from the array, just call .sample(): [1,2,3,4].sample() //=> a random element. I'm releasing these code snippets into the public domain, under the ...

   Let's look at all scenarios one by one. In this answer, "generator" means "random number generator" that is an instance of torch.Generator, and not Python's generator. Scenario 1. This scenario is straightforward. When one iterates a RandomSampler created without generator supplied, the

9. True random generation in Java - Stack Overflow

   stackoverflow.com/questions/381037

   The NSA and Intel’s Hardware Random Number Generator. To make things easier for developers and help generate secure random numbers, Intel chips include a hardware-based random number generator known as RdRand. This chip uses an entropy source on the processor and provides random numbers to software when the software requests them.

10. Get a random item from a JavaScript array - Stack Overflow

    stackoverflow.com/questions/5915096

    var item = jQuery.rand(items); This plugin will return a random element if given an array, or a value from [0 .. n) given a number, or given anything else, a guaranteed random value! For extra fun, the array return is generated by calling the function recursively based on the array's length :)
