AttributeError: type object has no attribute "id" PYTHON
<p>So I was trying to make a basic python pong game when this error came up:
It seems to say that AttributeError: type object has no attribute "id" which I have no idea what it means.</p>

<pre><code>C:\Users\****\AppData\Local\Programs\Python\Python35-32\python.exe C:/Users/****/untitled/src/testing.py
Traceback (most recent call last):
  File "C:/Users/****/untitled/src/testing.py", line 113, in &lt;module&gt;
    ball.draw()
  File "C:/Users/****/untitled/src/testing.py", line 36, in draw
    if self.hit_paddle2(pos) == True:
  File "C:/Users/****/untitled/src/testing.py", line 53, in hit_paddle2
    paddle2_pos = self.canvas.coords(self.paddle2.id)
AttributeError: type object 'Paddle2' has no attribute 'id'

Process finished with exit code 1

<p>This is the code I used:</p>

canvas.pack()
tk.update()

<p>You need to pass instances of <code>Paddle</code> and <code>Paddle2</code> to <code>Ball</code> constructor.</p>

<pre><code>paddle = Paddle(canvas, 'blue')
paddle2 = Paddle2(canvas, 'blue')
ball = Ball(canvas, paddle, paddle2, 'red')
</code></pre>
