(Python3)- Use Turtle to make graphics- Random function to draw graphs

Kimo, which was often used in the past, and now Yahoo intellectuals, also stopped serving this year. I thought I would sort it out by myself, and I would also publish an English version for practicing English. If there is a grammatical error, please include more.

Random function to draw graphs:

from numpy import *
from random import random
import turtle
turtle.reset()
x = array([[.5],[.5]])
p = [0.85,0.92,0.99,1.00]
A1 = array([[.85, 0.04],
      [-0.04,.85]])
b1 = array([[0],[1.6]])
A2 = array([[0.20,-0.26],
      [0.23,0.22]])
b2 = array([[0],[1.6]])
A3 = array([[-0.15,0.28],
      [0.26,0.24]])
b3 = array([[0],[0.44]])
 
A4 = array([[0,0],
      [0,0.16]])
 
turtle.color("blue")
cnt = 1
while True:
  cnt += 1
  if cnt == 2000:
    break
  r = random()
  if r < p[0]:
    x = dot(A1 , x) + b1
  elif r < p[1]:
    x = dot(A2 , x) + b2
  elif r < p[2]:
    x = dot(A3 , x) + b3
  else:
    x = dot(A4 , x)
  #print x[1]
  turtle.up()
  turtle.goto(x[0][0] * 50,x[1][0] * 40 - 240)
  turtle.down()
  turtle.dot()
