Function: random_select
|
|
|
|
DOC_MSE_VERSION: since 0.3.7
|
|
|
|
--Usage--
|
|
> random_select(some_list, count: some_number, replace: some_boolean)
|
|
|
|
Randomly select a number of items from a list.
|
|
|
|
If the @count@ parameter is not given, then a single item is picked at random.
|
|
|
|
Otherwise @count@ ''different'' items are selected (selection without replacment).
|
|
Setting the @replace@ parameter allows the same item to occur more than once in the result (selection with replacment).
|
|
|
|
Since the result is random, calling the function twice will give a different answer.
