How to add a function with if statements (key movement) in a class (python/pygame)?

I need to program a game in pygame similar to pong, but with 1 player. Although there is one paddle and one ball, I'm required to make a class for the paddle and for the ball. I created the paddle class, drawn it, but I have problem with implementing the if statements for movement. Here's what I tried:

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 Draw(self, screen,):
        pygame.draw.rect(window, self.color, [self.x,self.y,self.width,self.height])

    def Keys(self, y, height):
        keys = pygame.key.get_pressed()

        if keys [pygame.K_UP]: 
            self.y -= 1
        if keys [pygame.K_DOWN]:
            self.y += 1

and then I added a separate function for the objects from the classes:

def Objects():
    paddle = Paddle(1150,250,20,100,black)
    paddle.Draw(window)
    paddle.Keys(250,100)

Again I want to add key movement in the class (since all paddles should have the same function). I should also mention that I'm not getting any error, but it doesn't work.

You must create the instance of Paddle before the application loop. Pass the object to the Objects function:

def Objects(surf, paddle):
    paddle.Draw(surf)
    paddle.Keys(250,100)

my_paddle = Paddle(1150,250,20,100,black)

while True:

    # [...]

    Objects(window, my_paddle)

    # [...]
