Make the Python Turtle screen self adjust to show what's been drawn?

Question

I've been trying to find an answer to this all over the internet, and just can't find anything that works.

Essentially, I'm building my very first program which is a digital spirograph. One of the features of this is that you can have the turtle randomly draw a shape using fairly chaotic variables.

My issue is that when I do this, the turtle almost always draws out of the borders of the turtle window, therefore not allowing the user to see the full completed drawing at the end.

Is there an easy way to have the screen resize to the bounds of what has been drawn after the turtle finishes?

I'm not sure if I should list my code as it's a few hundred lines long at this point, but if that is needed let me know.

Edit: Here is my code as it currently is written -

import turtle
import random

print("Random Mode? y/n")
crazy = raw_input()
crazy = str(crazy)
if crazy == 'y' :
    print("Would you like your random selection to be chaotic? y/n")
    chaos = raw_input()
    chaos = str(chaos)
    if chaos == 'y' :
        passes_r = random.randint(4,15)
        angle_r1 = random.randint(1,180)
        angle_r2 = random.randint(1,180)

        angle_r4 = random.randint(1,180)

resize the window using the following code in python

By the way your question is duplicated I think.

Python imaging, resize Turtle Graphics window

setup( width = 200, height = 200, startx = None, starty = None)

So when I do that, I get the error; NameError: name 'setup' in not defined. Am I supposed to enter this in a specific spot of the code? – CptLoveNipple Sep 29 '16 at 18:35
try this turtle.setup( width = 200, height = 200, startx = None, starty = None) – Randhaja Malshan Wanigasekara Sep 29 '16 at 18:47
That has definitely helped, the 'turtle.setup' iteration works. Unfortunately, the program is sometimes randomizing to such a degree that it's still outside the confines of the box. Thank you for the help though! – CptLoveNipple Sep 29 '16 at 18:58
Use the documentation of python turtle. It would help a lot. https://docs.python.org/2/library/turtle.html#turtle.setup – Randhaja Malshan Wanigasekara Sep 29 '16 at 19:01

Make the Python Turtle screen self adjust to show what's been drawn?
