I am trying to make some games using classes. But I got a problem when trying to make the ping pong game. I made 2 paddles and a ball but I just do not understand how should I make the collision between the paddles and the ball using classes. Sorry if my code is kind of unorganized and thank you for your help and patience

import pygame
from sys import exit 

pygame.init()

#Screen details
screen_width=1000
screen_height=700
screen=pygame.display.set_mode((screen_width,screen_height))


class Paddle():
    
    def __init__(self, x,y,width,height,color):
        self.x=x
        self.y=y
        self.width=width
        self.height=height
        self.color=color
        
    def drawing(self):
        display=pygame.display.get_surface()
        pygame.draw.rect(display,(self.color),(self.x,self.y,self.width,self.height),0)
        
        
    def moving1(self):
        self.k=pygame.key.get_pressed()
        if self.k[pygame.K_UP]:
            self.y-=1
        if self.k[pygame.K_DOWN]:
            self.y+=1
    
    def moving2(self):
        self.k=pygame.key.get_pressed()
        if self.k[pygame.K_p]:
            self.y-=1
        if self.k[pygame.K_u]:
            self.y+=1
            
            
class Ball():
    
    def __init__(self,posx,posy,radius,color,speed):
        self.posx=posx
        self.posy=posy
