microPython - simon game - problem with clearing an array

Question

I'm building a Simon game using lego's ev3 and microPython.

My code is attached underneath. I think I have a problem with each iteration emptying my array of pressings.

Thanks

        # check isn't working
        print("check:", check)
        print("colors:", len(colors))
        print("colorsTouch:", len(colorsTouch))
        print(colorsTouch)
        if(len(colorsTouch)==len(colors)):
            for i in range(len(colors)):
                if colors[i]!=colorsTouch[i]:
                    print("LOSE")
            check=False
            

(I would like after each player's turn to empty my array so it will be able to get new inputs. but unstead it seems to be that the pressings are piling up each turn)
