I need help with my python code I only use the graphics.py library because those were the instructions ... The code is about the Pong game so far I have created the objects and I have made the ball move and collide at the limits. ... my question is in the last part of the code where I put it as a comment .. I can't make the ball collide with the paddle. I don't know if they could help me in that part ... The problem is in the part that says #Paddle and ball collision ..... Here is my code:

from graphics import *

def paddleA_up(paddleA):

paddleA.move(0, -20)

def paddleA_down(paddleA):

paddleA.move(0, 20)

def paddleB_up(paddleB):

paddleB.move(0, -20)

def paddleB_down(paddleB):

paddleB.move(0, 20)

def main():

#Window

win = GraphWin("Pong Game", 600, 400)

win.setBackground("black")

#Score

#PaddleA

paddleA = Rectangle(Point(5,2), Point(10, 70))

paddleA.setOutline("white")

paddleA.setFill("white")

paddleA.draw(win)

paddleA.move(5, 170)

paddleA.setWidth(20)

#PaddleB

paddleB = Rectangle(Point(5,2), Point(10, 70))

paddleB.setOutline("white")

paddleB.setFill("white")

paddleB.draw(win)

paddleB.move(580, 170)

paddleB.setWidth(20)

#Ball

radius = 8

ball = Circle(Point(20, 20), radius)

ball.setOutline("white")

ball.setFill("white")

ball.draw(win)

ball.move(290,170)

dx = 1

dy = 1

#Move Paddle

while True:

key = win.checkKey()

yFloor = radius

yCieling = win.getHeight() - radius

xFloor = radius

xCieling = win.getHeight() - radius

ball.move(dx, dy)

if key == "o":

break

elif key == "Up":

paddleA_up(paddleA)

elif key == "Down":

paddleA_down(paddleA)

elif key == "w":

paddleB_up(paddleB)

elif key == "s":

paddleB_down(paddleB)

#Move Ball

elif ball.getCenter().getY() <= yFloor or ball.getCenter().getY() >= yCieling:

dy = -dy

elif ball.getCenter().getY() <= xFloor or ball.getCenter().getY() >= xCieling:

dx = -dx

if ball.getCenter().getX() > 630:

ball.move(290,170)

dx *= -dx

if ball.getCenter().getX() < -620:

ball.getCenter()

dx *= dx

#Paddle and ball collision

#if ((ball.getCenter().getX() > 580 and ball.getCenter().getX() < 580)

#and (ball.getCenter().getY() < paddleB.getCenter().getY() + 20

#and ball.getCenter().getY() > paddleB.getCenter().getY() - 20)):

#ball.getCenter()

#dx *= -dx
