How can I obtain random images with turtle?

I have a code. And I generated random fibers with turtle. But I would like to obtain 100 different randamized images. I will create a dataset. How can i change the code and obtain the 100 images in a file by turtle ?

from turtle import Screen, Turtle
from random import randint

width, height = 500,500
fiber_r = 35
fiber_num = 50
cursor_size = 20

screen = Screen()
screen.setup(width, height)

fiber = Turtle()
fiber.hideturtle()
fiber.color('black')
fiber.shape('circle')
fiber.shapesize(fiber_r / cursor_size)
fiber.speed('fastest') 
fiber.penup()

fibers = []

for _ in range(fiber_num):
    fiberr = fiber.clone()
    fiberr.setposition( \
        randint(fiber_r - width/2, width/2 - fiber_r), \
        randint(fiber_r - height/2, height/2 - fiber_r) \
    )

    while any(map((lambda a: lambda b: a.distance(b) < fiber_r)(fiberr), fibers)):
        fiberr.setposition( \
            randint(fiber_r - width/2, width/2 - fiber_r), \
            randint(fiber_r - height/2, height/2 - fiber_r) \
        )

    fiberr.showturtle()
    fibers.append(fiberr)

screen.exitonclick()
