Pygame

Question

this is my code for a grid in pygame:
class Grid:
def __init__(self, x, y):
self.x = x
self.y = y
def draw(self):
pygame.draw.rect(screen, GREY, [self.x * WIDTH, self.y * HEIGHT, WIDTH, HEIGHT], 1)
pygame.display.update()
cols = 22
rows = 16
WIDTH = 20
HEIGHT = 20
BLACK = (0, 0, 0)
GREY = (127,127,127)
grid = [0 for i in range(cols)]
for node in range(cols):
grid[node] = [0 for node in range(rows)]
for x in range(cols):
for y in range(rows):
grid[x][y] = Grid(x, y)
for x in range(cols):
for y in range(rows):
grid[x][y].draw()
how to I get the vertices of each square?
