I am trying to make a drawing board in pygame but I want to be able to change the opacity using RGBA but it doesn't seem to be working, my code below:

n = 0
z = 0
i9 = 1
circle = []
long = 0
drawing_name = ''
load_name = ''
th = False
fill = r,g,b,a
WHITE = 255,255,255
file = 0
surf = pg.image.load('dot.png')
surf.fill((r,g,b))
color_ = pg.cursors.Cursor((20,20), surf)
pg.mouse.set_cursor(color_)
screen = pg.display.set_mode((1440,900),pg.FULLSCREEN)
pg.display.set_caption('Drawing board')
screen.fill(WHITE)
#pg.mouse.set_visible(False)
font1 = pg.font.SysFont('Chalkduster', 50)
font2 = pg.font.SysFont('Chalkduster', 25)
text1 = font1.render('What do you want to name your artwork:', True, (0, 0, 0))
textRect1 = text1.get_rect()
textRect1.center = (700, 500)
text2 = font1.render(drawing_name, True, (0, 0, 0))
textRect2 = text2.get_rect()
textRect2.center = (700, 500)

textRect4 = text4.get_rect()
textRect4.center = (700, 500)

textRect5 = text5.get_rect()
