Do we have "not in" in RobotFramework?

Hi!

I am trying to add new element to the list if it was not there before.

Run Keyword If ${itemText} not in ${Infostring} Append To List ${Infostring} ${itemText}

But i got error Evaluating expression ’ not in ’ failed: SyntaxError: invalid syntax
How to solve this problem?

Yes we do, the syntax error is related to using ${var} rather than $var, here is the correct syntax:

Run Keyword If $itemText not in $Infostring Append To List ${Infostring} ${itemText}

More explanations on what syntax is expected by Run Keyword If for its condition: Evaluating expressions

Also ${Infostring} must be a list for Append To List to be able to work with it.

See whole example working on playground.

Stylewise you could use a the IF statement which makes the line probably more readable:

IF    $itemText not in $Infostring    Append To List    ${Infostring}    ${itemText}

That should work with Robot Framework >=4

If you like, checkout the user guide for more information on IF/ELSE syntax at Robot Framework: Robot Framework User Guide
