python - I drew a Ball from class and It's stuck in the same place (python3/pygame)

Question

I have a Ball class and I drew a ball from that class. No matter what coordinates I put the ball is either stuck in the low middle part of the window or dissapears completely

#windowsize is (1200, 600)

class Ball():

def __init__(self,x,y,radius,color):
    self.x = x
    self.y = y
    self.radius = radius
    self.color  = color

def Draw(self,screen):
    pygame.draw.circle(window,self.color,[self.x,self.x],self.radius)

ball   = Ball(600,300,8,red)

while loop:
    ball.Draw(window)
    pygame.display.flip

Answer 1

There are 2 typos:

The parentheses are missing after pygame.display.flip

pygame.display.flip

pygame.display.flip()

The ball is drawn at [self.x,self.x] rather than [self.x,self.y]:

pygame.draw.circle(window,self.color,[self.x,self.x],self.radius)

pygame.draw.circle(window,self.color, [self.x, self.y], self.radius)
