The error about the code

I want to set the random change of the rendering time of the cross-shaped gaze point, so I entered the syntax of the random presentation time. I imported the shuffle function. Shuffle can randomly sort all elements of the sequence .I created the sequence name as d, including six rendering times, but my code keeps reporting errors. Can someone help me answer what’s wrong?

A comma should be added to the digital interval in the d sequence.


Thank you!!
