Pick a random element from list/array of strings in netLogo

Question

I am new programmer in netlogo. I waned to know how can I pick a random string from a list/array of strings in netLogo? If anyone can please guide me, I will be very much thankful. Thanks

PS : I have done efforts on my part, I only know how to pick a random number from a number range like this

random-float (PRICE * 0.20) ;For float value (price is an integer defined by me)
random round (DifferenceAmt * 0.10) ; For random rounded amount

Simply use one-of, e.g.:

print one-of [ "a" "b" "c" ]

will print either "a", "b" or "c", at random.

I noticed that you were asking for both lists and arrays. Note that one-of doesn't work with arrays from the array extension, but those can be converted to a list with array:to-list, so you can do: one-of array:to-list my-array. If speed is crucial, you could also do array:item my-array one-of n-values array:length my-array [ ? ]. But unless you have a very specific need for an array, you probably should not be using one.

Thank you so much for your help sir. This will do just fine for now :)

My pleasure. And by the way, the "fast" array version should have been: array:item my-array random array:length. (I don't think I was quite awake when I suggested using n-values for that...)
