No more than 3 correct answers in a row shown on the same side of the screen

Hi Everyone !

I am trying to create a number comparison task, in which 2 digits are shown side by side and the participant has to decide which is larger. Participants click ‘7’ if the correct answer is on the left side, and ‘9’ for the right side. I currently have 24 trials which are defined in excel. I have a loop which plays my trials in a random order. All of this is currently working well.

Even though my loop is set to random, I would like to ensure the correct answer is not shown more than 3 consecutive times on the same side.

I am quite new to PsychoPy and don’t have any experience with coding. Is this possible to do in the builder? Or please may someone help my with the coding?

Many thanks!
