I would just have used map to make that a lot more simple:

print map { "$_|" } @my_list

[download]

And a design pattern that you should start to recognize is that as soon as you see the concatenation operator, you should be thinking about changing that to a list. So 

$my_id_list .= $my_list[$i]."|";

[download]
should change to 
push ( @my_id, "$my_list[$i]|" );

[download]
Later, after you're done with the loop, you can join all of the list elements together.

And if your code also removes the last "|" from the strong that you're building, then you can do 

push ( @my_id, $my_list[$i] );

[download]
during the loop and 
join('|',@my_id);

[download]
at the end of the loop to get the same result.
