Python: AttributeError: 'Pong' object has no attribute 'render' -

-

came across error while following python tutorial create game pong:

traceback (most recent call last):   file "c:/users/gavin/pycharmprojects/lmagpong/game.py", line 98, in <module>     main()   file "c:/users/gavin/pycharmprojects/lmagpong/game.py", line 91, in main     pong.render(screen) attributeerror: 'pong' object has no attribute 'render'

this code used create pong object(render @ bottom):

class pong(object):     def __init__(self, screensize):          self.screensize = screensize          self.centerx = int(screensize[0] * 0.5)         self.centery = int(screensize[1] * 0.5)          self.radius = 8          self.rect = pygame.rect(self.centerx - self.radius,                                 self.centery - self.radius,                                 self.radius * 2, self.radius * 2)          self.color = (100, 100, 255)          self.direction = [1, 1]          self.speed = 2           self.hit_edge_left = false         self.hit_edge_right = false      def update(self, player_paddle=none, ai_paddle=none):          self.centerx += self.direction[0] * self.speed         self.centery += self.direction[1] * self.speed          self.rect.center = (self.centerx, self.centery)          if self.rect.top <= 0:             self.direction[1] = 1         elif self.rect.bottom >= self.screensize[1] - 1:             self.direction[1] = -1          if self.rect.right >= self.screensize[0] - 1:             self.hit_edge_right = true         elif self.rect.left <= 0:             self.hit_edge_left = true          def render(self, screen):             pygame.draw.circle(screen, self.color, self.rect.center, self.radius, 0)             pygame.draw.circle(screen, (0, 0, 0), self.rect.center, self.radius, 1)

and main function(called render near bottom):

def main():     pygame.init()      screensize = (640, 320)      screen = pygame.display.set_mode(screensize)      clock = pygame.time.clock()      pong = pong(screensize)      running = true      while running:         # fps limiting/reporting phase         clock.tick(64)          # event handling phase         event in pygame.event.get():             if event.type == quit:                 running = false          # object updating phase         pong.update()           if pong.hit_edge_left:             print('you won')             running = false         elif pong.hit_edge_right:             print('you lose')             running = false          # rendering phase         screen.fill((100, 100, 100))          pong.render(screen)          pygame.display.flip()      pygame.quit()

im new python im trying hang of this, im not sure if im making simple mistake or im doing wrong, im following tutorial.
