How can I get new random values with each blank in ReplaceAll?

Question

Is there any way to get different values for different blanks with ReplaceAll[]? For example, I would like to do something like:

{_,_,_}/. _Blank -> RandomInteger[{1, 10}]

But, the output comes out as all the same random integer for each blank, such as:

{4, 4, 4}

Is there an efficient way to get an output that is more random, like:

{4, 7, 1}

,as shown above?

Thanks!

Answer 1

You can simply change the Rule -> to RuleDelayed :> to give

{_, _, _} /. _Blank :> RandomInteger[{1, 10}]

(*{5, 1, 3}*)

Answer 2

Just for variety: you can also temporarily redefine Blank as RandomInteger[{1,10}]& using Block:

Block[{Blank = RandomInteger[{1, 10}] &}, {_, _, x, y, _, z}]

{5, 7, x, y, 5, z}
