title: Its my first python project and i have been trying to move a simple rectangle down the screen as tetris blocks fall down but failing
body: <p>I have tried many other methods, including creating a rectangle and iterating the y coordinate but that creates a long line which i do not want. This is my OOB approach to it, which is not great, but please bear with me as i am a beginner. I have also tried out the code in the documentation and it also created a line of rectangles. Kindly help me</p>
  <pre><code>class Rectangle:
      def __init__(self, x, y):
          self.x = x
          self.y = y
          self.rect=pygame.draw.rect(window,(255,0,0),pygame.Rect(x,y,50,50))
      def draw_shape(self,x,y):
          self.rect=pygame.draw.rect(window,(255,0,0),pygame.Rect(x,y,50,50))
          pygame.display.update()
      def move_shape(self,x):
          for i in range(0,10):
              x=x+50*i
              self.draw_shape(x, 0)
  
  recT= Rectangle(0,0)
  recT.draw_shape(0,0)
  while running==True:
      for event in pygame.event.get():
          if event.type==pygame.QUIT:
              running=False
      recT.move_shape(0)
      pygame.display.update()
  </code></pre>
