PyGame surface locked during blit [duplicate] - pygame

Question

I am trying to draw text to a screen in a space above a bunch of rects that are all in the 2d array square. When i try and draw text to the screen it says that "Surfaces must not be locked during blit."
I have tried unlocking, it makes no difference.

You're using a PixelArray:
pixArray = pygame.PixelArray(screen)
But using a PixelArray locks your Surface, as stated in the documentation:
During its lifetime, the PixelArray locks the surface, thus you explicitly have to delete it once its not used anymore and the surface should perform operations in the same scope.
Just remove the line, since you're not using it anyway.
