I hope this helps you . quick question: , Here is my attempt using splice: code :
var a = [1,2,3,4,5,6,7,8,9,10];var sample = [];
sample.push(a.splice(Math.random()*a.length,1));
sample.push(a.splice(Math.random()*a.length,1));
function sample_range(range, n) {
var sample = [];
for(var i=0; i<n; i++) {
sample.push(range.splice(Math.random()*range.length,1));
}
return sample;
}
var sample = sample_range([1,2,3,4,5,6,7,8,9,10], 2);
Array.prototype.sample_range = function(n) {
var sample = [];
for(var i=0;i<n;i++) {
sample.push(this.splice(Math.random()*this.length,1));
}
return sample;
};
var sample = [1,2,3,4,5,6,7,8,9,10].sample_range(2);

this will help I'm using smarty v2.6 and I want to generate random distinct numbers. I'm looking for an efficient, fast way to do it using already provided Smarty functions. This is my code for generating 5 random numbers (but not distinct): , if you really need to do it in smarty templates method 1 code :
{assign var="distinct_numbers" value=array_fill(1,15,'x')}
{assign var="distinct_numbers" value=array_keys($distinct_numbers)}
{assign var="x" value=shuffle($distinct_numbers)}
{* result *}
{foreach from=$distinct_numbers item="value"}
{$value} |
{/foreach}
1 | 7 | 3 | 10 | 4 | 8 | 6 | 14 | 13 | 12 | 2 | 5 | 11 | 9 | 15 |

 Will this query generate distinct random numbers in Mysql?

wish help you to fix your issue The answer is not always because the result of your query will be only the distinct values of your random numbers so if you generate the same random number 2 times, that number will appear only 1 time (you will lose 1 record).

Any of those help you could use random.choice: code :
import numpy as np
np.random.choice(a=np.arange(4), size=2, replace=False)
np.random.choice(a=4, size=2, replace=False)
