ball has no collision with moving paddle

Question

the ball doesn't collide with the top moving paddle. I have to make a game like pong but vertical. But i can't figure out with my programming skills how the ball doesn't collide with the top paddle. I think it has to do with the hit paddle_2 but i don't really know how the paddle_pos works.

def hit_paddle_2(self, pos):
        paddle_2_pos = self.canvas.coords(self.paddle_2.id)
        if pos[2] >= paddle_2_pos[0] and pos[0] <= paddle_2_pos[2]:
            if pos[3] >= paddle_2_pos[1] and pos[3] <= paddle_2_pos[3]:
                return True
        return False

def draw(self):
        self.canvas.move(self.id, self.x, self.y)
        pos = self.canvas.coords(self.id)
        if pos[1] <= 0:
            self.y = 3
        if pos[3] >= self.canvas_height:
            self.hit_bottom = True
        if self.hit_paddle_2(pos) == True:
            self.y = -3
        if pos[0] <= 0:
            self.x = 3
        if pos[2] >= self.canvas_width:
            self.x = -3

class Paddle_2:
    def __init__(self, canvas, color):
        self.canvas = canvas
        self.id = canvas.create_rectangle(0, 0, 200, 10, fill=color)
        self.canvas.move(self.id, 200, 150)
        self.x = 0
        self.canvas_width = self.canvas.winfo_width()
        self.canvas.bind_all('<KeyPress-a>', self.turn_left)
        self.canvas.bind_all('<KeyPress-d>', self.turn_right)

   def draw(self):
        self.canvas.move(self.id, self.x, 0)
        pos = self.canvas.coords(self.id)
        if pos[0] <= 0:
             self.x = 0
        elif pos[2] >= self.canvas_width:
            self.x = 0
