[PyGame] Pong game key.event problem

[erickDarko]

I'm writing a simple pong game with OOP and i have this issue when i move the left and right paddle, they don't move in a continuous way, i have to press t he up down key every time to move them.
Here is the code of main loop:

class MainLoop:
	while True:
		for event in pygame.event.get():
			if event.type == pygame.QUIT:
				pygame.quit()
				quit()
		
			if event.type == pygame.KEYDOWN:

				if event.key == pygame.K_w:
					if pad_left.y >= 2:
						pad_left.y -= 10
				elif event.key == pygame.K_s:
					if pad_left.y <= display_height - pad_left.height:
						pad_left.y += 10
				elif event.key == pygame.K_UP:
					if pad_right.y >= 2:
						pad_right.y -= 10
				elif event.key == pygame.K_DOWN:
					if pad_right.y <= display_height - pad_right.height:
						pad_right.y += 10

		if ball.x <= 0 or ball.x >= display_width:
			ball.x = display_middle[0]
			ball.y = display_middle[1]
			ball.speed_x = 5
			ball.speed_y = 5
			if ball.x <= 0:
				pad_right.score += 1
				ball.speed_x = abs(ball.speed_x)
			elif ball.x >= display_width:
				pad_left.score += 1
				ball.speed_x = -ball.speed_x
			
		# pad colission
		if ball.x <= pad_left.width + ball.radius and ball.y >= pad_left.y+10 and \
		ball.y <= pad_left.y+pad_left.height+10:
			if ball.y >= pad_left.y + 20 and ball.y <= pad_left.y + 60:
				ball.speed_x -= 1
				ball.speed_y -= 2
			else:
				ball.speed_x = -5
				ball.speed_y = 5
			ball.speed_x = -ball.speed_x
			
		if ball.x + ball.radius >= pad_right.x and ball.y >= pad_right.y+10 and \
		ball.y <= pad_right.y+pad_left.height+10:
			if ball.y >= pad_right.y + 20 and ball.y <= pad_right.y + 60:
				ball.speed_x += 1
				ball.speed_y += 2
			else:
				ball.speed_x = 5
				ball.speed_y = -5
			ball.speed_x = -ball.speed_x

		display.fill(background) # <~~
	
		drawText(pad_left.score, white, 70, (display_middle[0]-95,0))
		drawText(pad_right.score, white, 70, (display_middle[0]+60,0))
		pad_left.drawPad()
		pad_right.drawPad()
		#pygame.draw.line(display, white, (display_middle[0],0), (display_middle[0], display_height), 2)
		[ pygame.draw.rect(display, white, (display_middle[0], y, 6, 6)) for y in range(6, display_height, 15)]
		ball.drawBall()
		
		# GAME OVER SCREEN
		if pad_left.score == 1 or pad_right.score == 1:
			display.fill(background)
			drawText('GAME OVER', white, 70, ((200, (display_middle[1]//2))))
			if pad_left.score == 1:
				drawText('Player 1 won', white, 40, (display_middle[0]-145, display_middle[1]))
			if pad_right.score == 1:
				drawText('Player 2 won', white, 40, (display_middle[0]-145, display_middle[1]))
			pad_left.score = 0
			pad_right.score = 0
			pygame.display.update()
			pygame.time.wait(1500)
			if pygame.key.get_pressed()[pygame.K_RETURN]:
				pass
		else:
			pygame.display.update()
		
		clock.tick(30)

if __name__ == '__main__': 
	MainLoop()

I'm learning OOP so if it's something I can do to improve on this code I'll be grateful. thank you.

if event.type == pygame.KEYDOWN:

this checks for a single event, not consistently holding down a key.

Put this not within the event loop but in the main game loop

keys = pygame.key.get_pressed()
if keys[pygame.K_UP] or keys[pygame.K_w]:
    pass
#etc.
