Robot Framework dynamic list variable - robotframework

Question

I have a for loop in which I would like to create list and add values to there.
FOR ${i} IN RANGE 3
*Create list List_${i}
Add values to list
END
How could I do it?
So that after exit the for loop, I would have list_1 & list_2 and list_3
Meaning I can create dynamic variable like this:
FOR ${idx} IN RANGE 3
${var_name} = Catenate SEPARATOR=_ var ${idx}
Set Suite Variable ${${var_name}} ${idx}
END
Maybe it is some easy way to do the same with #list ?
This does not work:
FOR ${i} IN RANGE 3
Log ${i}
${var_name}= Catenate SEPARATOR=_ TEST_NAME ${i}
Log ${var_name}
#{${${var_name}}}= Create List data
END

Answer 1

I think this is the answer:
FOR ${i} IN RANGE 3
Log ${i}
Set Suite Variable #{List${i}} #{EMPTY}
Append To List ${List${i}} ${i}
END

Answer 2

Note sure if this is exactly what you are looking for; but, I'll try to help.
First, lists cannot be empty; so you will need at least an initial value which you can then remove (or ignore) when you iterate thru the list. That said, I can suggest you create a For-Loop which returns is List-of-Lists since your "loop range may change".
Test-Dynamic-Lists-Creation
${listOfLists} Create List initial-value
FOR ${index} IN RANGE 3
${List_$index} Create List initial-value
Append To List ${listOfLists} ${List_$index}
END
Comment Removes the first value from the list.
Remove From List ${listOfLists} ${0}
Log List ${listOfLists}
Return From Keyword ${listOfLists}
