How to draw shapes using the grouping thing

I just learned how to group stuff in pygame but when I try to use it to draw a sprite it says: " ExternalError: TypeError: Cannot read property 'left' of undefined on line 32"

Here is my code:

import pygame   from pygame import *    screen = pygame.display.set_mode((600, 600))    blocks = pygame.sprite.Group()    class Block():      def __init__(self, x, y, w, h, typ):          super().__init__()          self.x = x           self.y = y          self.w = w           self.h = h           self.typ = typ      def draw(self):          pygame.draw.rect(screen, (0, 0, 0), (self.x, self.y, self.w, self.h))  class Player():      def __init__(self, x, y):          super().__init__()          self.x = x           self.y = y          self.accX = 0           self.accY = 0      def draw(self):          pygame.draw.rect(screen, (0, 0, 0), (self.x, self.y, 20, 20))  player = Player(0, 0)    while True:      Blocks = Block(0, 0, 100, 50, 1)      blocks.add(Blocks)      blocks.draw(screen)      for event in pygame.event.get():          if event.type == pygame.QUIT:              pygame.quit()      pygame.display.update()
