/random with multiple ranges?

[unborn quiver]

I want to randomly generate numbers from multiple ranges; /random 1..3, 7..9 and it will give any of: 1,2,3,7,8,9
Only two ranges seems easy:
/store [...] random 1..2
if [...] 1 run random 1..3
if [...] 2 run random 7..9

Doing that for a very large amount of ranges is going to be really annoying though, is there a better way?

You could use macros, but even then you'd need a command for each range you want all at once

you can take a random element of the array

[slow owl]

data modify storage main random_array set value [1,2,3,7,8,9]
execute store result storage main macros.i int 1 run random value 0..5
function get_number with storage main macros

function get_number

$execute store result score #random main_score run data get storage main random_array[$(i)]
