Can't figure out how to get my mouse cursor on the center of the rect

Question

When i hit play my cursor seems to be on the top left corner of the rect, i am very fresh to using thonny/pygames and can't figure out how to get my mouse cursor to be in the center of the rect.

Any help would be greatly appreciated, thanks! :)

        pygame.display.flip()  # transfers build screen to human visable screen

Create a pygame.Rect object with the size of the player and set the center position of the rectangle by the mouse cursor position:

player1 = pygame.Rect(0, 0, 50, 50)
player1.center = mouse_position
pygame.draw.rect(screen, red, player1)

Note, a pygame.Rect has a bunch of virtual attributes, which can be used to get an set its size and position.
