Saving multiple drag and drop data in output

WIN 10, PsychoPy3 2020.2.5 (but I use version 2020.2.4, because version 5 creates errors with the coloring of the background and stimuli in pavlovia)

Dear PsychoPy community, I need your help with some code elements. In my experiment I created a drag and drop game where participants can drag and drop green and red pieces (circles) over various polygon stimuli. At the end participants will have drawn and dragged 42 pieces over 42 different polygons. I need to save the final position of every piece so that I know, which color piece was dragged over which polygon. I am struggeling with that part because what I tried so far does not do what I need.
What I need is basically this:
#if polygon contains a piece --> save piece.name and the polygon name in two columns (cvs/excel file etc.)

I am able to save the data while participants drag and drop the pieces, but that does not tell me what the final positions are with certain. As soon as another piece touches a polygon, this will be saved in the excel file, even if it was not dropped on the polygon.
I have also tried to use the “checkAnswer” function from @dvbridges code but I couldn’t figure out how to adapt it to my needs succesfully…

I’ll post my current code below (Python part, but I will need a JS version too…). If you have a solution or tip I would be very happy!

#Begin Experiemnt:
def createPiece(piece, pos, name):
    return visual.ImageStim(win, image=piece.image, name=piece.name, size=piece.size, pos=pos, opacity=0.5, interpolate=True)

def drawPicked(picked):
    for each in picked:
        each.draw()

def movePicked(picked, mouseMulti, grabbed):
    #move piece if it is already being moved 
    if grabbed is not None and mouseMulti.isPressedIn(grabbed): #JS 'undefined'
        grabbed.pos = mouseMulti.getPos()
        return grabbed
    else: #move newly clicked piece
        for piece in picked:
            if mouseMulti.isPressedIn(piece) and grabbed is None: #JS 'undefined'
                return piece
