Trying to make a rect move and point to the cursor in PyGame

I'm porting a game from Scratch to Pygame, in hopes of learning more about Pygame.

I got the movement down, it's a smooth type of movement where you can slide around and I'm setting the variables x and y to the player x and y. And I plugged the x and y to the blit to put the player in the scene, and it works just fine.

The problem is when I try to get the player to look at the mouse pointer while he moves around. I already have a function to rotate the player to the mouse pointer and it also works just fine, but when I put that function into the loop, it seems to work fine but the further right you go the less accurate it gets.

I have no idea why it does that, but I'm very annoyed since this is the only thing hindering my progress.

pygame.key.set_repeat(16,16)
screen = pygame.display.set_mode([width, height])
player = pygame.image.load("images/player.png")
player_center = (
    x+(width-player.get_width())/2,
    y+(height-player.get_height())/2
)
print(player_center)
player_pos = (x,y)
cursor_pos = list(screen.get_rect().center)

    global speedY

    speedY = speedY + int(keyboard.is_pressed('s'))-int(keyboard.is_pressed('w')) * 0.9
    speedY = speedY * 0.9
    y += speedY
    speedX = speedX + int(keyboard.is_pressed('d'))-int(keyboard.is_pressed('a')) * 0.9

    screen.fill((255, 255, 255))
    
    screen.blit(rotimage, (x,y))
    
    pygame.display.flip()

    fpsClock.tick(FPS)
# Done! Time to quit.
pygame.quit()
