I can't work out way my ball and right paddle won't collide in pong pygame

Question

I've been trying to work out how to make collision logic for pong in pygame for a CS class.

I've tried multiple things and it works 99.9% of the time for the left paddle which isn't a issue but however, it only works about 10% of the time for the right paddle and I can't figure out why.

Thank you in advanced :)

from pygame.constants import K_DOWN, K_UP, K_s, K_w

pygame.init()
width=640
height=480


white = (255,255,255)
black = (0,0,0)
red = (255, 0, 0)

screen = pygame.display.set_mode((width, height ))
pygame.display.set_caption('Pong')
blue = (0,0,255)

#Setting set frame rate
clock = pygame.time.Clock()

#Global Paddle Settings
paddleWidth = 20
paddleHeight = 100
paddleSpeed = 10

#Left Paddle
lPaddleX = 20
lPaddleY = 200

#Right Paddle
rPaddleX = 600
rPaddleY = 200

#Ball
ballHeight = 25
ballWidth = 25
ballStartX = 310
ballStartY = 240
ballX = 310
ballY = 240
ballStartSpeed = 1
ballSpeed = 2
ballDirection = [0,1]
#[xdirection, ydirection]

running = True
while (running): # loop listening for end of game
    keys = pygame.key.get_pressed()
    # dt = clock.tick(30)
    
    #Ball Physics
        #Movement Logic
    if ballDirection[0] == 1 and ballDirection[1] == 1:
        ballX += ballSpeed
        ballY += ballSpeed
    if ballDirection[0] == 1 and ballDirection[1] == 0:
        ballX += ballSpeed
        ballY -= ballSpeed
    if ballDirection[0] == 0 and ballDirection[1] == 1:
        ballX -= ballSpeed
        ballY += ballSpeed
    if ballDirection[0] == 0 and ballDirection[1] == 0:
        ballX -= ballSpeed
        ballY -= ballSpeed
        
        #Top and Bottom Colision Logic
    if ballY <= 0:
        ballDirection[1] = 1
    if (ballY + ballHeight) >= height:
        ballDirection[1] = 0
    
    #Paddle Colision Logic
        #Right Paddle    
    if (ballX + ballWidth) == (rPaddleX) and ballY <= (rPaddleY + paddleHeight) and (ballY + ballHeight) >= rPaddleY:
        ballDirection[0] = 0
        ballSpeed += 1
        #Left Paddle
    if ballX == (lPaddleX + paddleWidth) and ballY <= (lPaddleY + paddleHeight) and (ballY + ballHeight) >= lPaddleY:
        ballDirection[0] = 1
        ballSpeed += 1
        
    #Right Paddle Controls
    if keys[K_UP]:
            if rPaddleY >=0:
                rPaddleY -= paddleSpeed
    if keys[K_DOWN]:
        if (rPaddleY + paddleHeight) <= height:
            rPaddleY += paddleSpeed
    
    #Left Paddle Controls
    if keys[K_w]:
        if lPaddleY >= 0:
            lPaddleY -= paddleSpeed
    if keys[K_s]:
        if (lPaddleY + paddleHeight) <= height:
            lPaddleY += paddleSpeed  
          
    screen.fill(black)
    
    # pygame.draw.rect(screen, blue, (ax,ay,squareWidth,squareHeight), 0)

    # pygame.draw.rect(screen, red, (bx,by,squareWidth,squareHeight), 0)
    
    #Paddles
    pygame.draw.rect(screen, white, (lPaddleX,lPaddleY,paddleWidth,paddleHeight), 0)
    pygame.draw.rect(screen, white, (rPaddleX,rPaddleY,paddleWidth,paddleHeight), 0)
    pygame.draw.rect(screen, red, (ballX,ballY, ballWidth, ballHeight),0)
    
    pygame.display.flip() # paint screen one time
    pygame.time.wait(5)


    


    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False
#loop over, quite pygame
pygame.quit()

I can't work out way my ball and right paddle won't collide in pong pygame
