Qualcuno mi può aiutare a trovare il problema nel file? Volevo creare le Frattale di mandelbrot

from turtle import color
import pygame
import os

os.environ['SDL_VIDEO_CENTERED'] = '1'

width, height = 1920,1080
win = (width, height)
screen = pygame.display.set_mode(win)
xaxis = width/1.80 + 150
yaxis = height/2
scale = 450
interations = 60 #risoluzione frattale

for iy in range(int(height/2+1)):
    for ix in range(width):
        z = 0+0j
        c = complex(float(ix-xaxis)/scale, float(iy-yaxis)/scale)
        x = c.real
        y = c.imag
        y2 = y*y
        q = (x-0.25)**2+y2
        if not(q*(q+(x-0.25)) < y2/4.0 or (x+1.0)**2+y2 < 0.0625):
            for i in range(interations):
                z = z**2+c
                if abs(Z) > 2:
                    V = 765*i/interations
                    if v > 510:
                        color = (155, 155, v%255)
                    elif v > 255:
                        color = (100, v%255, 255)
                    else:
                        color = (0, 0, v%255)
                    break
                else:
                    color = (0, 0, 0)
        screen.set_at((ix,iy), color)
        screen.set_at((ix, height-iy), color)

pygame.display.update()
run = True
while run:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            run = False
pygame.quit()

Prima modifica: Aggiunto "from turtle import color"
