"Missing required argument" when argument is there [closed]

Traceback (most recent call last):
  File "c:\Users\davey\OneDrive\Documents\Python\Game\game.py", line 64, in <module>
    bullet.draw(wn)
TypeError: bullet.draw() missing 1 required positional argument: 'wn'

It literally shows bullet.draw(wn) above it, and then says that wn isn't there?

What am I doing wrong here? I know that it is passing self through like it should, but why is it not reading wn?

This is the code being called:

class bullet(object):
    def __init__(self, x, y, color):
        self.x = x
        self.y = y
        self.velocity = 5
        self.color = color
        
    def draw(self, wn):
        pygame.draw.circle(wn, self.color, (self.x, self.y), 1)

and this is where its being called:

for bullets in bulletcount:
        bullet.draw(wn)

What is going on?
